Wilson's Theorem provides a necessary and sufficient condition for primality using factorials.
Wilson's Theorem states that for any prime p, (p minus 1)! is congruent to minus 1 modulo p. Consequently, adding 1 makes the result divisible by p exactly. In the Brocard equation, n! plus 1 undergoes a divisibility flip at prime thresholds. This flip enforces structural constraints on factorization. As n crosses each prime boundary, the arithmetic landscape shifts abruptly. The requirement that the result be a square must survive every such transition. Only three small n manage to pass all prime checkpoints simultaneously. The structural gauntlet tightens with each new prime.

Prime thresholds act as structural gates in factorial arithmetic. Each new prime introduces fresh congruence conditions. The divisibility flip compounds alignment difficulty. Square compatibility must persist across expanding prime territory. Computational evidence suggests no further success beyond small values. Structural pressure intensifies with scale.
The dramatic aspect lies in simplicity. A theorem about divisibility governs numbers with millions of digits. Each prime enforces discipline silently. The Brocard equation must survive repeated reversals. The survivors at 4, 5, and 7 appear almost miraculous against this systematic resistance.
