Non-increasing order

We gave a new criterion for graphical partitions. We derive a new recursion formula, which allows the computation of the number g(n) of graphical partitions of weight n for up to n 900.A partition of weight n is a nonincreasing sequence of nonnegative integers (1, 2, . . . , k, . . .) whose sum is n. The weight is denoted by ||. The number of nonzero elements in the sequence is the length of the partition denoted by l(). The set of all partitions of weight n is denoted by P(n).
