Abstract

We study cyclically presented groups of type F\mathfrak{F} to determine when they are perfect. It turns out that to do so, it is enough to consider the Prishchepov groups, so modulo a certain conjecture, we classify the perfect Prishchepov groups P(r,n,k,s,q)P(r,n,k,s,q) in terms of the defining integer parameters r,n,k,s,qr,n,k,s,q. In particular, we obtain a classification of the perfect Campbell and Robertson's Fibonacci-type groups H(r,n,s)H(r,n,s), thereby proving a conjecture of Williams, and yielding a complete classification of the groups H(r,n,s)H(r,n,s) that are connected Labelled Oriented Graph groups.
