Also known as p-primary group, primary group, p-group

In mathematics, specifically group theory, given a prime number p, a '''p-group' is a group in which the order of every element is a power of p. That is, for each element g of a p-group G, there exists a nonnegative integer n such that the product of pn copies of g, and not fewer, is equal to the identity element. The orders of different elements may be different powers of p''.

In mathematics, specifically group theory, given a prime number p, a '''p-group' is a group in which the order of every element is a power of p. That is, for each element g of a p-group G, there exists a nonnegative integer n such that the product of pn copies of g, and not fewer, is equal to the identity element. The orders of different elements may be different powers of p.

Abelian p-groups are also called 'p-primary or simply primary'.
