%N Even abundant numbers (even numbers n whose sum of divisors exceeds 2n).
%C Set difference of abundant numbers A005101 by odd abundant numbers A005231.
%C While the first even abundant number is 12 = 2^2*3, the first odd abundant is 945 = 3^3*5*7, the 232th abundant number! Thus the first 231 terms of this sequence are the same as for sequence A005101 of abundant numbers.
%C Dickson proves that, for each m and n, there are only a finite number of these numbers having a factor 2^m and n distinct odd prime factors. - T. D. Noe, Mar 31 2011
