Do we have a thread about bigram method in the context mentioned by Anton?
Quote: For the simplest example, one may substitute not single letters but, say, bigrams. Take the word "date", if "da" maps to "po" and "te" maps to "lo", then "date" maps to "polo", and there's no 1:1 mapping between single characters (instead, it exists for bigrams). The decipherer would in vain consider the two "o" characters to be the same.
