Subgroup ($H$) information

Description:$C_2\times C_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(320\)\(\medspace = 2^{6} \cdot 5 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(6,7)(10,11), (6,7)(8,14,13,9,15,12)(10,11), (8,13,15)(9,12,14)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $C_2\times \GL(2,\mathbb{Z}/4):F_5$
Order: \(3840\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.
