Subgroup ($H$) information

Description:$C_2\times C_4^2$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $\langle(6,7)(10,11), (2,5)(3,4), (2,5)(3,4)(6,10,7,11)(12,15)(13,14), (2,5)(3,4)(6,7)(8,9)(10,11)(12,13)(14,15), (2,4,5,3)(6,10,7,11)(8,9)\rangle$ 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) and a $p$-group (hence elementary and hyperelementary).

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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$(C_5\times A_4).C_2^4.C_2^6$
$\operatorname{Aut}(H)$ $C_2^6:S_4$, of order \(1536\)\(\medspace = 2^{9} \cdot 3 \)
$\operatorname{res}(S)$$C_2^2\wr C_2$, of order \(32\)\(\medspace = 2^{5} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(64\)\(\medspace = 2^{6} \)
$W$$C_2$, of order \(2\)
