How can I list the sizes of centers of groups of order $288$ in GAP? By GAP we know that there are $1045$ groups of this order by the command below:
I want to obtain
Size(Center(G[i])) for $i = 1, \dots, 1045$
In fact I want to compute the difference between values of
NrConjugacyClasses of corresponding
G[i], for $i = 1, \dots, 1045$.
