If you take a look at one segment of the honeycomb e.g.
-<_>-
you can see that lattice points at -o< and >o- segments do not have the same "neighbours". It is important to notice that both the arrangement and orientation have to be the same at any point in Bravais lattice.
For more detail see Ashcroft - Solid State Physics (pg. 64).

Why honey comb is in hexagonal prism?
honeycomb is a mass of hexagonal wax cells built by honey bees in their nests to contain their larvae and stores of honey and pollen.Beekeepers may remove the entire honeycomb to harvest honey. Honey bees consume about 8.4 pounds of honey to secrete one pound of wax,[1] so it makes economic sense to return the wax to the hive after harvesting the honey, commonly called "pulling honey" or "robbing the bees" by beekeepers. The structure of the comb may be left basically intact when honey is extracted from it by uncapping and spinning in a centrifugal machine-the honey extractor. Fresh, new comb is sometimes sold and used intact as comb honey, especially if the honey is being spread on bread rather than used in cooking or to sweeten tea.Broodcomb becomes dark over time, because of the cocoons embedded in the cells and the tracking of many feet, called travel stain by beekeepers when seen on frames of comb honey. Honeycomb in the "supers" that are not allowed to be used for brood (e.g. by the placement of a queen excluder) stays light coloured.Numerous wasps, especially polistinae and vespinae, construct hexagonal prism packed combs made of paper instead of wax; and in some species (like Brachygastra mellifica), honey is stored in the nest, thus technically forming a paper honeycomb. However, the term "honeycomb" is not often used for such structures.Honeycomb geometryThe bees begin to build the comb from the top of each section. When filled with honey, the bees seal the cells with wax. Close up of an abandoned Apis florea nest, Thailand. The hexagonal grid of wax cells on either side of the nest are slightly offset from each other. This increases the strength of the comb and reduces the amount of wax required to produce a robust structure.The axes of honeycomb cells are always quasi-horizontal, and the non-angled rows of honeycomb cells are always horizontally (not vertically) aligned. Thus, each cell has two vertical walls, with "floors" and "ceilings" composed of two angled walls. The cells slope slightly upwards, between 9 and 14 degrees, towards the open ends.There are two possible explanations for the reason that honeycomb is composed of hexagons, rather than any other shape. One, given by Jan Brożek, is that the hexagon tiles the plane with minimal surface area. Thus a hexagonal structure uses the least material to create a lattice of cells within a given volume. Another, given by D'Arcy Wentworth Thompson, is that the shape simply results from the process of individual bees putting cells together: somewhat analogous to the boundary shapes created in a field of soap bubbles. In support of this he notes that queen cells, which are constructed singly, are irregular and lumpy with no apparent attempt at efficiency.[2]The closed ends of the honeycomb cells are also an example of geometric efficiency, albeit three-dimensional and little-noticed. The ends are trihedral (i.e., composed of three planes) sections of rhombic dodecahedra, with the dihedral angles of all adjacent surfaces measuring 120°, the angle that minimizes surface area for a given volume. (The angle formed by the edges at the pyramidal apex is approximately 109° 28' 16" (= 180° - arccos(1/3)).)The three-dimensional geometry of a honeycomb cell.The shape of the cells is such that two opposing honeycomb layers nest into each other, with each facet of the closed ends being shared by opposing cells.Opposing layers of honeycomb cells fit together.Honeycomb of the Giant honey bee Apis dorsata in a colony aggregation in Srirangapatnna near BangaloreIndividual cells do not, of course, show this geometric perfection: in a regular comb, there are deviations of a few percent from the "perfect" hexagonal shape. In transition zones between the larger cells of drone comb and the smaller cells of worker comb, or when the bees encounter obstacles, the shapes are often distorted.In 1965, László Fejes Tóth discovered that the trihedral pyramidal shape (which is composed of three rhombi) used by the honeybee is not the theoretically optimal three-dimensional geometry. A cell end composed of two hexagons and two smaller rhombuses would actually be .035% (or approximately 1 part per 2850) more efficient. This difference is too minute to measure on an actual honeycomb, and irrelevant to the hive economy in terms of efficient use of wax, considering that wild comb varies considerably from any mathematical notion of "ideal" geometry
How much does a half gallon of honey weigh?
The weight of honey depends on the type of honey you have. The moisture content of the honey also will affect the weight. For planning purposes, the average weight for a half gallon of honey would be about 6 pounds (2.73 kilograms).
Prove that comb space in a topological space is an example for connectednes but not locally connectedness?
The comb space C=([0,1]X0) union (KX([0,1]) union (0X{0X1]} where K is the set 1/n where n is an integer. It is made up of vertical lines that make it look like a comb. Each of these vertical lines is joined at the bottom to the y axis. You can see immediately the C is connected since each vertical segment is connected and each vertical segment meets the horizontal segment which is also clearly connected. Now, we need to show it is NOT locally connected. Note the following are equivalent: (TFAE) 1. A space X is locally connected 2. Components of open subsets in X are open ( in X) 3. X has a basis consisting of connected subsets Let V be an open ball with the usual metric in the comb space, which I will call C. Let's put V at the point (0,1/2) and the ball has radius 1/4. The vertical segments of the comb will be the components of V. All of these are open except for ones along the y axis. So we have the {0,y| which is an element of R2 1/4<y<3/4} is not open. This violates condition 2 and we have C is not locally connected. Note the comb space is path connected as is the deleted comb space. But the comb space is not path connected.
Is the side centered cube a bravais lattice?
Hi, No the side centered lattice is not a Bravais Lattice as the lattice doesn't look the same from an atom on the corner of the cube and an atom in the middle of a vertical edge of the cube (they don't even have the same number of neighbors). In fact, the side centered lattice is a simple cubic lattice with a basis of two atoms.
Why is end- centered tetragonal bravais lattice not possible?
An end-centered tetragonal Bravais lattice cannot exist because it would violate the constraints of translational symmetry required for a Bravais lattice. In a tetragonal lattice, the unit cell must have four sides of equal length and right angles, which cannot be maintained if an end-centered arrangement is introduced.

What is space lattice?
Space lattice is a three-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal. Space lattice is also known as crystal lattice or Bravais lattice.
Why Bravais lattices are 14 in number?
Bravais lattices are classified based on their lattice symmetries, leading to 14 possible combinations of translational and rotational symmetries. These 14 Bravais lattices represent all possible ways in which a lattice can be arranged in 3D space while maintaining translational periodicity. Each Bravais lattice has unique characteristics that define its geometric arrangement.
How many bravais lattices exist?
There are 14 Bravais lattices in 3D space, which are categorized into 7 crystal systems based on the lattice parameters and symmetry. Each lattice type represents a unique way in which points can be arranged in space to form a crystal structure.
Does honey comb contain honey?

How do you remove honey from a honey comb?
To remove honey from a honeycomb, you can cut the comb out of the beehive and then place it in a centrifuge, which spins the comb to extract the honey. Another method is to crush the comb and then strain it through a fine mesh to separate the honey from the wax.
What are bravais 14 unit cells?
It's not precisely clear what you mean. If you mean "what are the 14 3-dimensional Bravais lattices", then you'd be better served by looking in a crystallography book with diagrams. The Wikipedia page about Bravais lattices also shows them.

What are the Miller-Bravais indices for hexagonal planes?
The Miller-Bravais indices for hexagonal planes are a set of three integers (h, k, l) that represent the orientation of a plane in a hexagonal crystal structure. These indices are used to identify and describe different planes within the hexagonal lattice.
