Derived length: | $2$ |
The subgroup is nonabelian, monomial (hence solvable), metabelian, and an A-group.
Ambient group ($G$) information
Description: | $C_4^4.C_{24}$ |
Order: | \(6144\)\(\medspace = 2^{11} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $2$ |
The ambient group is nonabelian and metabelian (hence 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_4^2.(C_2^4\times C_{12}).C_2^6.C_2^3$ |
$\operatorname{Aut}(H)$ | $C_2^4.S_4^2$, of order \(9216\)\(\medspace = 2^{10} \cdot 3^{2} \) |
$W$ | $A_4$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \) |
