There are 6 basic dot locations in Braille, enough to create about 720 different characters. The basic 26 characters are the English letters A to Z and numbers (1 to 9 and zero, which are the same as letters A to J but indicated by a separate "number" symbol). There are special characters for accented letters in various languages. Characters may also be used for contractions, conjunctions, prepositions, music notation, and special symbols in math and various scientific fields.

There are 256 possible combinations of dots in 8-dot braille (if you include a blank cell as a character).

Almost all braille is made up of six dots. However, some refreshable Braille displays use eight dots in each cell to save room and make reading quicker.
Two make combinations you would take 2x1=2 combinations only
One bar code can have anywhere from 30 to 70 different combinations within itself. How many combinations are in the world is not known.

By using a method that involves moving their hands across a page of many small raised bumps that they feel with their fingertips. The bumps are arranged in different formations and each formation equals a different letter, number or symbol. This method is known as braille.

Braille is an arrangement of raised dots on a surface that form numbers, letters, and words. Blind persons feel the dots with their fingertips to recognize the patterns. The technique is similar to holding a pair of dice in your hand and feeling the dents that tell you what number is on each face. You can feel how many dents there are, which tells you what number it is. Braille is the same except the letters are raised bumps. Each set of raised bumps is a different letter. Just like the dice. People that read Braille learn what each letter feels like. Both hands are used in reading Braille, but mainly the index fingers.

Since a number can have infinitely many digits, there are infinitely many possible combinations.
Braille is a writing system that is used by blind and visually impaired. Braille was developed by Louis Braille who went blind as a child and developed the system at age 15. The braille system is raised bumps that are found on paper and each represent something different. The braille alphabet can be found on many websites.
