Subgroup ($H$) information

Description:$A_4\times C_2^4$
Order: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Index: \(15\)\(\medspace = 3 \cdot 5 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(6,7)(8,9), (6,7)(12,13), (1,3,5)(6,7)(10,11)(12,13), (1,5)(3,4)(6,7)(8,9)(12,13), (1,4)(3,5)(6,7)(8,9)(12,13), (8,9), (10,11)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, monomial (hence solvable), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_2^4:\GL(2,4)$
Order: \(2880\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, an A-group, and nonsolvable.

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)$$S_3\times S_4\times S_5$, of order \(17280\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 5 \)
$\operatorname{Aut}(H)$ $S_4\times A_8$, of order \(483840\)\(\medspace = 2^{9} \cdot 3^{3} \cdot 5 \cdot 7 \)
$\operatorname{res}(S)$$S_4\times S_3^2$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$C_3\times A_4$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
