Wolstenholmes sats

Inom matematiken är Wolstenholmes sats ett resultat som säger att för alla primtal p > 3 gäller kongruensen:

${\displaystyle {2p-1 \choose p-1}\equiv 1{\pmod {p^{3}}}.}$

En ekvivalent formulering är kongruensen:

${\displaystyle {ap \choose bp}\equiv {a \choose b}{\pmod {p^{3}}}.}$

Satsen bevisades av Joseph Wolstenholme 1862.
