In mathematics a trimorphic number is a number whose cube ends in the number itself. For example, 4^{3} = 64, 24^{3} = 13824, and 249^{3} = 15438249. The first few trimorphic numbers are: 1, 4, 5, 6, 9, 24, 25, 49, 51, 75, 76, 99, 125, 249 ... (sequence A033819 in OEIS) Every automorphic number is also a trimorphic number, but there are trimorphic numbers which are not automorphic (such as 4, 9 and 24).
