Use with the (group-theory) tag. Refers to questions concerning finite groups of prime power order or infinite p-groups such as Prüfer groups, pro-p-groups, and Tarski monsters. This tag is not for p-adic number systems.

This tag is for questions specifically pretaining to finite p-groups and their properties, such as isoclinism, schur covers and projective representations, and cohomology. The tag can also be used for questions about infinite p-groups such as Prüfer groups, pro-$p$-groups, or Tarski monsters. This tag is not for use with p-adic number systems, though it may be used for the $p$-adic integers $\displaystyle\varprojlim \mathbb{Z}/(p^n\mathbb{Z})$.
