%N Integers m such that sigma(m) + sigma(8*m) = 18*m.
%C This is the case h = 8 of the h-perfect numbers as defined in the Harborth link.

%F a(n) = 2^A002236(n) * A050524(n).
%e 34 is a term since sigma(34) + sigma(8*34) = 612, that is 18*34.
%o (PARI) isok(m) = sigma(m) + sigma(8*m) == 18*m;
%Y Cf. A000203, A000396, A002236, A050524, A136539, A281993, A330413.
