Sequences

The braille letters are divided into three sequences.

A to J

The first sequence covers the letters a to j and uses the top two rows of dots (dots 1 to 4) in different combinations.

1-atoj1

K to T

Letters k to t, add dot 3, to the previous sequence above.

1-ktot

U to Z

The final sequence adds dot 6 to the previous sequence of letters k to t, to make the letters u, v, x, y and z. Note w is different, this is because it did not appear in the original french alphabet. So, w was added later and appears as j with dot 6 added to the cell to make w. See below.

1-utoz

Letters u to z of the Braille Alphabet

So, when the alphabet is explained in this way, these sequences make it quite easy to work out. Letters a to j form the basis of the braille code, so once these are learned, the rest follows easily. (Reference: #2)
