Subgroup ($H$) information

Description:$C_2\times A_4^2:D_4$
Order: \(2304\)\(\medspace = 2^{8} \cdot 3^{2} \)
Index: \(2\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,4,8)(3,6,7), (9,16)(10,15)(11,14)(12,13), (1,8)(2,4)(3,5)(6,7), (1,4) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is normal, maximal, a semidirect factor, nonabelian, and monomial (hence solvable).

Ambient group ($G$) information

Description: $C_2^7:S_3^2$
Order: \(4608\)\(\medspace = 2^{9} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, 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_5^4.\OD_{16}$, of order \(36864\)\(\medspace = 2^{12} \cdot 3^{2} \)
$\operatorname{Aut}(H)$ $A_4^2.C_2^4.C_2^3$
$\operatorname{res}(S)$$C_2^6.D_6^2$, of order \(9216\)\(\medspace = 2^{10} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2\)
$W$$A_4^2:C_2^3$, of order \(1152\)\(\medspace = 2^{7} \cdot 3^{2} \)
