A set of three theorems about finite groups describing the existence, conjugacy and number of maximal p-subgroups (Sylow subgroups) for a given prime p dividing the group's order. Proved by Ludwig Sylow, they are the single most used tool for analyzing the structure of finite groups.
Facts
StatementFor every prime factor p of the order of a finite group G, there exists a Sylow p-subgroup of G of order p^n, the highest power of p dividing the order of G. Every subgroup of order p^n is a Sylow p-subgroup, all Sylow p-subgroups of G for a given prime p are conjugate to each other, and their number is congruent to 1 modulo p. 1 Classification
