%N Numbers n that are the product of four distinct primes such that x^2+y^2 = n has integer solutions.
%C Union of 2*A264498 and A264499. - _Ray Chandler_, Dec 09 2019
%H Ray Chandler, <a href="/A248712/b248712.txt">Table of n, a(n) for n = 1..10000</a>
%e 2210 is in the sequence because 2210 = 2*5*13*17, and x^2+y^2=2210 has integer solutions (x,y) = (1,47), (19,43), (23,41) and (29,37).
%e 32045 is in the sequence because x^2 + y^2 = 32045 = 5*13*17*29 has solutions (x,y) = (2,179), (19,178), (46,173), (67,166), (74,163), (86,157), (109,142) and (122,131).
%Y Cf. A248649, A264498, A264499.
