%N Larger members of g-reduced amicable pairs a < b such that sigma(a) = sigma(b) = a + b + gcd(a,b).
%C The lesser counterparts are in A054573.
%C 435 appears twice since it has 2 lesser counterparts, 270 and 280. - _Amiram Eldar_, Jan 19 2019
%e 182 is in the sequence since it is the larger member of the pair (140, 182), and sigma(140) = sigma(182) = 336 = 140 + 182 + gcd(140, 182).
