<Verb>CcGroup(N,f):: GOuterGroup, StandardCocycle --> CcGroup</Verb><P/>
Inputs a <M>G</M>-outer group <M>N</M> with nonabelian cocycle describing some
extension <M>N \rightarrowtail E \twoheadrightarrow G</M> together
with standard 2-cocycle
<M>f\colon G \times G \rightarrow A</M> where <M>A=Z(N)</M>. It returns
the extension group
determined by the cocycle <M>f</M>. The group is returned as a cocyclic
group.
<P/>
This function is part of the HAPcocyclic package of functions implemented by Robert F. Morse.
