# Busy Beaver BB(10) Exceeds Graham's Number

A Hacker News post notes that the Busy Beaver function value BB(10) is greater than Graham's Number. This shows how extraordinarily fast Busy Beaver numbers grow and gives a striking example from computability theory. It matters because it demonstrates that tiny Turing machines can encode values far beyond well-known huge numbers.

**Importance:** 2/5
