Stirling's approximation becomes more accurate as n increases, reducing relative error significantly.
Stirling's approximation expresses n! as roughly square root of 2 pi n times (n over e) to the n. This estimate exposes the immense growth trajectory of factorials. Taking square roots of n! yields expressions scaling near (n over e) to the n over 2 power. The precision requirement for n! plus 1 to equal an exact square becomes increasingly stringent. Small relative errors translate into enormous absolute mismatches. As n grows, the window for exact equality narrows dramatically. The analytic estimate aligns with computational silence beyond small n. Approximation highlights structural improbability.

Asymptotic analysis often predicts feasibility boundaries before exhaustive search confirms them. Stirling's formula clarifies that factorial magnitude escalates beyond square alignment tolerance quickly. Even minor deviations in exponent structure magnify at scale. The analytic curve diverges sharply from square lattice behavior. Probability collapses under magnitude pressure. The formula provides intuition for rarity.
The elegance of approximation intensifies the contrast. A smooth analytic curve explains abrupt empirical silence. Mathematics can forecast impossibility without enumerating every case. The Brocard equation becomes a lesson in asymptotic foresight. Structure dominates chance. Growth overwhelms coincidence.
