%N Values of A000010(m) such that no solutions share the same prime signature.
%H Max Alekseyev, <a href="http://home.gwu.edu/~maxal/gpscripts/">PARI scripts for various problems</a> (see invphi.gp there).
%e 1 is a term as the only solutions A000010(1) and A000010(2) do not share the same prime signature.
%e 2 is a term as the only solutions A000010(3), A000010(4), and A000010(6) do not share the same prime signature.
%e 12 is not a term since A000010(21) = A000010(26) are solutions and the prime signature of 21 and 26 is {1,1}.
