Whatever you think appropriate. Personally, I do not consider that
asymptotic as a great discovery. ;)

It can be shown that gcd(A000045(i),A000032(i)) <= 2.
So, A000045(i) and A000032(i) have a non-trivial factor in common iff
they both are even.
And that takes place only when i is a multiple of 3.
