Summary:
Define a “nuclear partition” to be an integer partition with no part equal to one. In this study we prove
a simple formula to compute the partition function p(n) by counting only the nuclear partitions of n, a vanishingly
small subset by comparison with all partitions of n as n → ∞. Variations on the proof yield other formulas for p(n),
as well as Ramanujan-like congruences and an application to parity of the partition function.
