If crystal planes and directions in hexagonal system are indexed using Miller Index, then the crystallography equivalent planes have indices which appear dissimilar. To overcome this, Miller-Bravais Index is used.

In short meaning: Miller-Bravais index, used to identify a plane in a hexagonal or rhombohedral structure.

The four digit of Miller-Bravais indices: (hkil). The i is always the negative of the sum of h and k. The h k l is determined similar like the Miller Index system.

The Miller index is a notation system for lattice structure in crystallography. By convention, a negative number isn't represented the same way as a negative integer in math (like "-3" for instance.) Instead, the negative sign simply goes above the integer, as a small bar.
