| 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: | |

| --- ------------ --- ------ | |
| 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 | |
