If this is some kind of code, this might help:
E is the most commonly used letter, followed by t, o, a and n
T is the most common letter at the beginning of a word, E is the most common letter at the end of a word.
A and I are the only single letter words in English. The words of, to, and in are the most frequently used two letter words; the and and are the most frequent three letter words; that is the most four letter word.
The most common double letters are ll, ee, oo, tt, ff, rr, nn, pp and cc. Th, he, re, er, and in are the most frequent two-letters combinations. The, ing, ion and ent are the most frequent three letter combinations.
N is the constant that most commonly follows a vowel.
