Yes, I agree ; the proof given there is correct.

The %N A132410 could be a comment in A117950
but I don't know if it's worth it :
I'm not sure if I understand correctly whether this was the intended
meaning of Richard's comment, but you could give an infinity of
Polynomials of the form
 P = (X-3)Q(X)^2
for which the solutions to P(x)=Y^2
are x=n^2+3.

However, A117950 should start at offset n=0 with a(0)=3 added before a(1)=4
to avoid another dupe submission.

So Richard's o.g.f. given for A132410 would be OK for A117950.

But there are 3 xref's to A132410, namely in

They should be changed to A117950 if the other one is deleted.
