trimorphic number

Given a base b integer


where d1 is the least significant digit and dk is the most significant, if it’s also the case that the k least significant digits of n3 are the same of those of n, then n is called a trimorphic numberMathworldPlanetmath.

All automorphic numbers (with m=1) are also trimorphic numbers, but not all trimorphic numbers are 1-automorphic.
