Square Constraints

Given is an integer N. How many permutations (P_0,P_1,\cdots,P_{2N-1}) of (0,1,\cdots,2N-1) satisfy the following condition?

  • For each i (0 \leq i \leq 2N-1), N^2 \leq i^2+P_i^2 \leq (2N)^2 holds.

Since the number can be enormous, compute it modulo M.

Constraints

  • 1 \leq N \leq 250
  • 2 \leq M \leq 10^9
  • All values in input are integers.

Input

Input is given from Standard Input in the following format:

N M
