comment A Difficult Application of Modular Arithmetic
Your explanation doesn't seem to match your numbers. Why is the 6 not doubled to 12 in the first step? How does the 2 in {2,5,1} go to 0? 2*2 + 4 is not 0 mod 5.

A cube root has three possible values. To ensure you get a real one, you could use Surd. For example Surd[x^2, 3].

comment How to draw all paths from (1,1) to (n,n) by move (+1, 0) or (0, +1)?
