Dear Group: Consider the following sequence {0,3,2,1} which can be related to the reference k: {0,1,2,3} as 4-k (mod 4). I've tried to use FindSequenceFunction on problems like the example above without success. I understand I'm working within the context of modular arithmetic... Does anyone have a suggestion on how to use Mathematica to tackle this problem? Alex
