### How to analyse trigrams?

Trigrams (groups of three 3 letters) are used in some encryptions in cryptography. There are 2 main modes of appearance of trigrams:

- A trigram can appear when a single character (or a bigram) is encrypted by 3 characters.

Example: A can become 'BCD', or AB can become CDE

- A trigram can be derived from the encryption of another trigram

Example: ABC can become DEF
