Subgroup ($H$) information

Description:$C_2^3\times C_{10}$
Order: \(80\)\(\medspace = 2^{4} \cdot 5 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\langle(1,5,3,2,4), (6,7)(10,11), (1,4,2,3,5)(8,9)(10,11), (6,7)(8,9)(12,13)(14,15), (12,13)\rangle$ 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 elementary for $p = 2$ (hence hyperelementary).

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