Using the modular ring Z4, it is shown that the row structures of xnyn, x, y odd, n = 2m, are incompatible with the row structures of zn. Even though some structures are close, the right-end-digits (REDs) are quite distinct. The analysis shows how the effort to find counter-examples for such theorems may be drastically reduced.

It is shown that the two essential 2-Fibonacci sequences have bases with respect to function ψ with length 24 and their extensions have bases with respect to function ψ with length 216.
