About Trimorphic

A trimorphic number is one whose cube ends with the number itself. For example, 4³ = 64, 24³ = 13824, 25³ = 15625.

Key features

  • Same idea as automorphic but for the cube instead of the square.
  • The sequence ends in ...625 for 25, 125, ... and ...376 for 376, 9376, ....

Examples:

1, 4, 5, 6, 9, 24, 25, 49, 51, 75, 76, 99, 125, 251, 376, 499, 501, 624, 625
