# Braille Dots

A standard braille cell consists of six dots arranged in three rows and two columns. Each dot can be specifically identified by its number as follows:

Dot | Position | Row | Column
1 | top-left | 1 | 1
2 | middle-left | 2 | 1
3 | bottom-left | 3 | 1
4 | top-right | 1 | 2
5 | middle-right | 2 | 2
6 | bottom-right | 3 | 2

Computer braille has introduced a fourth row at the bottom.

Dot | Position | Row | Column
7 | below-left | 4 | 1
8 | below-right | 4 | 2

A picture may make this numbering convention easier to understand:

    1 o o 4
    2 o o 5
    3 o o 6
    7 o o 8
