%N A025316 Numbers that are the sum of 2 distinct nonzero squares in 6 or more ways.
%C A025316 Subsequence of A025297. But sequences A025316 and A025297 are different. 2*5^10 = 19531250 = 3125^2 + 3125^2 (not distinct squares) = 2879^2 + 3353^2 = 2125^2 + 3875^2 = 1825^2 + 4025^2 = 955^2 + 4315^2 = 625^2 + 4375^2 is not in A025316. - _Vaclav Kotesovec_, Feb 27 2016
%C A025316 Numbers in A025297 but not in A025316 are exactly those numbers of the form 2*p_1^(2*a_1)*p_2^(2*a_2)*...*p_m^(2*a_m)*q^10 where p_i are primes of the form 4k+3 and q is a prime of the form 4k+1. Thus 2*5^10 is the smallest term in A025297 that is not in A025316. - _Chai Wah Wu_, Feb 27 2016
