Subgroup ($H$) information

Description:$C_6^2:Q_8$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Index: \(2\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, c^{2}d^{2}, b^{4}, d^{3}, d^{2}, b^{2}, b^{4}c^{3}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2^3.\SOPlus(4,2)$
Order: \(576\)\(\medspace = 2^{6} \cdot 3^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3:S_3.C_2^6.C_2^2$
$\operatorname{Aut}(H)$ $D_6^2.C_2^5$
$\operatorname{res}(\operatorname{Aut}(G))$$D_6^2:C_2^3$, of order \(1152\)\(\medspace = 2^{7} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$S_3^2:C_2^2$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
