# Reference request: groups of order $p^4$.

I am looking for a textbook or a paper which include the classification of groups of order $p^4$ ($p$ is prime) using generators and relations. In particular I like to understand which group $G$ "exist" for the odd $p$'s and do not exist for $p=2$.

• Have you looked in Berkovich? This seems like it must be in there somewhere. – Tobias Kildetoft Jan 7 '15 at 9:13
• This was done by Burnside, and you can find the tables and proofs in his book "Theory of Groups of Finite Order" (which is not hard to find online). – Derek Holt Jan 7 '15 at 9:18
