comment Cover the grid graph with simple cycles
@san excellent finding. I am even more curious as of what is the formula for $C(n,m)$. By the way, feel free to post your comments as an answer for just these two cases (hopefully with explanation). This is not the question which will attract hundreds of views even with the bounty, so I highly doubt that some would answer it.

comment Find all natural values n, that $\sqrt{P_{2}(n)}$ is also a natural number
@JoonasIlmavirta if the general solution is too hard, you can show me how to come up with a solution for $3n^2 - 2n - 1$

@AndréNicolas yes, I assumed the modular exponentiation method that runs in O(log exp)
