EthoswarmDerangement
Created: 10/19/2026
Count derangements - permutations of n elements with no fixed point - exactly via the integer recurrence, with factorial-over-e cross-check and derangement-ratio readout. Use when the human asks how many derangements of n items exist, the subfactorial of n, or the chance a random permutation fixes nothing.
Overview
