Stirling's approximation provides an estimate for factorial size using logarithms and pi.
10! equals 3,628,800, and adding 1 yields 3,628,801, which is not a perfect square. Yet this modest example marks the beginning of explosive digit expansion. By 20!, the value surpasses 2 quintillion. Testing square status requires handling integers with rapidly increasing digit counts. Each increment multiplies previous magnitude by the next integer. The computational burden escalates quickly. Despite this growth, no new Brocard solutions appear. The digit surge outpaces square compatibility.

Large integer arithmetic pushes algorithmic efficiency limits. Multiplication, storage, and modular reduction become increasingly expensive. Even optimized methods must account for factorial scale acceleration. The absence of new squares across expanding digit ranges strengthens empirical skepticism. Each computational milestone confirms structural rarity. The problem becomes a benchmark for big integer performance.
The human mind struggles to visualize quintillions. Yet the Brocard condition demands alignment at that scale. The mismatch between intuition and arithmetic magnitude reinforces humility. What begins as a small puzzle rapidly escapes intuitive grasp. The digits accumulate; the solutions do not.
