**Triliteral** cipher encryption uses a **triliteral** alphabet (**triliteral** = 3 letters, or aloso called **trifid** or ternary = 3 items). Each letter is then replaced by a corresponding triple of 3 letters.

__Example:__ Encrypt `DCODE` with the alphabet `A=AAA`, `B=AAB`, `C=AAC`, `D=ABA`, etc. The encrypted message is: `ABA AAC BBC ABA ABB`

**Triliteral** Decryption requires to know the trileteral alphabet used in order to perform a substitution.

__Example:__ The ciphered message `ABAAACBBCABAABB` have been encoded with the alphabet `A=AAA`, `B=AAB`, `C=AAC`, `D=ABA`, etc. The original plain text is `DCODE`.

It is possible to transform ciphertext in mono-alphabetical substitution and use dCode solver.

The ciphered message has 3 distinct characters equally distributed.

Main variants involve changing the alphabet. Another possibility is to switch to characters that are not A, B and C.

The list of permutations with repetition of 3 characters `A`, `B` and `C` is: AAA, AAB, AAC, ABA, ABB, ABC, ACA, ACB, ACC, BAA, BAB, BAC, BBA, BBB, BBC, BCA, BCB, BCC, CAA, CAB, CAC, CBA, CBB, CBC, CCA, CCB, CCC

The first **triliteral** alphabet appeared between 1550 and 1650
