Subgroup ($H$) information

Description:$C_2^3:D_6$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(7\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, d^{2}, c^{14}, b, c^{21}, d^{3}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is maximal, nonabelian, a Hall subgroup, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Ambient group ($G$) information

Description: $D_{42}:C_2^3$
Order: \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$2$

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

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_2^4.C_2^4.C_7.C_3^3.C_2^3$
$\operatorname{Aut}(H)$ $S_3\times C_2^6:S_4$, of order \(9216\)\(\medspace = 2^{10} \cdot 3^{2} \)
$\operatorname{res}(S)$$S_3\times C_2^6:S_4$, of order \(9216\)\(\medspace = 2^{10} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(6\)\(\medspace = 2 \cdot 3 \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
