%N Numbers n with property that n, n^2, n^3, and n^4 have the same set of digits (not counting repetitions).
%C If n is here then also 10*n is. But not vice versa: if the term n is multiple of 10 then not necessarily n/10 is the term; e.g., 129738560, 172836950, 175438290 are terms but 12973856, 17283695, 17543829 not.
