%N A262094 Orders m for which the only perfect digital invariants of order m are 0 and 1.
%C A262094 a(1), a(2), ... are the indices m for which A255668(m)=2, also A003321(m)=0, also A046761(m)=1.
%C A262094 The values seem to appear in clusters.
%e A262094 a(3)=12 because there's no solution to x=(x_{12}...x_1x_0)_{10} = x_{12}^{12}+...+x_1^{12}+x_0^{12} except x=0 and x=1.
%Y A262094 Cf. A003321, A046761, A255668.
