Is there any command in GAP to generate a Hamiltonian group of an order given?

I'm looking for in GAP-Reference Manual, but i don't find anything.

Bujalance, Etayo & Gamboa define a Hamiltonian group like a kind of group wich all subgroups are normal subgroups.

  • $\begingroup$ Regarding the structure of a H. group, it would be a case that you give any arbitrary order and want GAP to call the group of the kind. $\endgroup$

    $\begingroup$ There isn't such a function per se, but as the structure of Hamiltonian groups is just a direct product of $Q_8$ with a suitable abelian group, they could be constructed easily that way. $\endgroup$

  • $\begingroup$ This function may be useful to determinate if the group is hamiltonian: Hamiltonian:=function(G) ls:=AllSubgroups(G);; nm:=Filtered(ls,n-> IsNormal(G,n));; a:=nm=ls;; Print(a); end; $\endgroup$
