For example A can be mapped to D while B can be mapped to R, and so are the rest being mapped to a different alphabet. Recall that Caesar Cipher has a key space of 25, Monoalphabetic Substitution can have a key space of 26 x 25 x 24 x…….x 1, i.e. 26! (This time we have a different assumption, we assume that each alphabet can be mapped to itself).
