[GAP Forum] Elements of the same order

[Joe Bohanon]

It's better to use the conjugacy classes first as GAP will have a hard (or
impossible) time doing this when n>=10.

ccls:=ConjugacyClasses(SymmetricGroup(n));
2ccls:=Filtered(ccls,i->Order(Representative(i))=2);
Concatenation(List(2ccls,Elements));
