Subgroup ($H$) information

Description:$C_2^3\times F_5$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $\langle(6,9)(7,8)(10,11), (2,5,3,4)(6,9)(7,8)(10,11), (2,3)(4,5)(6,9)(7,8), (6,9)(7,8), (7,8), (1,4,3,2,5)(6,9)(7,8)\rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2\times D_4\times S_5$
Order: \(1920\)\(\medspace = 2^{7} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, nonsolvable, and rational.

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_2^5.C_2^3.S_5$
$\operatorname{Aut}(H)$ $F_5\times C_2^3:\GL(3,2)$, of order \(26880\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \cdot 7 \)
$\operatorname{res}(S)$$C_2^2\wr C_2\times F_5$, of order \(640\)\(\medspace = 2^{7} \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$C_2\times F_5$, of order \(40\)\(\medspace = 2^{3} \cdot 5 \)
