In mathematics a trimorphic number is a number whose cube (expressed in a given base) ends in the number itself. For example, 43 = 64, 243 = 13824, and 2493 = 15438249.
The first few trimorphic numbers in base 10 are:
Every automorphic number is also a trimorphic number, but there are trimorphic numbers which are not automorphic (such as 4, 9 and 24).
