The 6 dot positions with 3 rows are first interpreted as a binary number, a embossed dot presented by 1, a flat position by 0, the upper left position the most significant bit; the result is converted to base 10.
Written horizontally with six consecutive 0's or 1's, a(1)=100000=1, a(2)=101000=5, a(3)=110000=3, a(4)=110100=11, a(5)=100100=9, .. .
Letters A to Z are a(1) to a(22) - a(40) is W - a(24) to a(26). a(23) to a(39) are specific to French (essentially diacritical letters with an accent on the first E).
