%N a(n) = product of the positive "nonisolated divisors" of (2n). A divisor, k, of n is nonisolated if (k1) or (k+1) also divides n.
%C No odd integer has any nonisolated divisors.
%F a(n) = A007955(2n) / A134338(2n).  Chandler
%e The divisors of 2*10 = 20 are 1,2,4,5,10,20. Of these, 1,2,4,5 are the nonisolated divisors. So a(10) = 1*2*4*5 = 40.
%Y Cf. A134338.
