%N a(n) is the least perfect power whose digits can be rearranged in n different ways (including itself) to form perfect powers.
%C Do all terms except 4 start with 1?
%H David A. Corneth, <a href="/A337245/a337245.gp.txt">Examples n = 1..28 along the perfect powers</a>
%e a(3) = 169 = 13^2 as 169 is a perfect power and its digits can be permuted in three ways: 169 = 13^2, 196 = 14^2, and 961 = 31^2.
