1-mismatch sequences of a non-code word sequence, “CAAAA”. Idea behind finding 1-mismatch sequences of the sequence “CAAAA”. The two circles indicate the equivalence classes. The sequence “CAAAA” belongs to an equivalence class whose center is “AAAAA” that holds 3 of the 15 1-mismatch sequences. Two of the other sequences, “CAAAT” and “CAAGA”, belong to a equivalence class whose center is “CAAGT”.
