[seqfan] Easier formula for A232329?

[Alonso Del Arte]

I decided to look up 42n^2 to see if the system would recognize the
formula, as it does with 42n. I was surprised to get this result:

A232329: Integer areas A of the integer-sided triangles such that the
product of the inradius and the circumradius is of square length.

Obviously 3000 is not 42 times a square, nor is 6960. It could be that
42n^2 is a proper subsequence of A232329.
