Fermat numbers grow faster than factorial and standard exponential sequences.
Fermat numbers follow the formula 2^(2^n)+1. Unlike ordinary exponential growth, the exponent itself grows exponentially. This creates double-exponential expansion. F5 already exceeds four billion, while F6 surpasses 18 quintillion. By F10, the number contains more than 300 decimal digits. The growth outpaces standard exponential functions encountered in population or finance models. Such escalation quickly escapes intuitive comparison.

Double-exponential growth rarely appears outside theoretical mathematics. Most real-world systems plateau or stabilize. Fermat numbers do neither. Each increment multiplies previous scale beyond recognition. Computational feasibility collapses rapidly. Arithmetic abstraction races ahead of physical possibility.
This explosive pattern shapes why new Fermat primes are unlikely to be discovered casually. Even testing primality becomes a monumental task. The formula is simple; its consequences are overwhelming. Mathematics here demonstrates how compact notation encodes extreme magnitude. A small superscript hides astronomical expansion.
