One example of a monotone map would the simple substitution cipher mapping letters to numbers, so given \\( (A,\le_A) \\)= ({a,b, ... , z}, alphabetical order ) and \\( (B,\le_B) \\) = ({1,2, ... , 26}, numerical order), then the **monotone map** from \\(A\\) to \\(B\\) is \\(f : a \to 1 , b \to 2 , ... , z \to 26 \\).

apologies if my mathematical notation isn't correct...
