Subgroup ($H$) information

Description:$C_2^2\times S_4$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,5)(3,4)(8,9)(12,13), (6,7)(14,15), (6,14,7,15)(8,9), (6,7)(10,11), (1,5)(3,4)(6,7)(10,11)(12,13)(14,15), (6,10,14)(7,11,15)\rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is nonabelian, monomial (hence solvable), and rational.

Ambient group ($G$) information

Description: $C_2^3:F_5\times S_4$
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 $W = N_G(H) / Z_G(H)$.
