%N Minimal numbers with the same values for sigma_0(n) and sigma(n) as one or more other numbers.
%C Numbers n such that for some m > n, sigma(n) = sigma(m) and sigma_0(n) = sigma_0(m), but this does hold for any m < n.
%C Values are sorted by sigma(n), then by sigma_0(n).
%C See the a-file for a PARI program and more values.

%e sigma(14) = sigma(15) = 24, sigma_0(14) = sigma_0(15) = 4, so 14 is in the sequence. sigma(16) = sigma(25) = 31, but sigma_0(16) = 5 != sigma_0(25) = 3, so 16 is not in the sequence.
