Subgroup ($H$) information

Description:$C_6\times S_3$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(39\)\(\medspace = 3 \cdot 13 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a, b^{3}, c, b^{2}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $\He_3:D_{26}$
Order: \(1404\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 13 \)
Exponent: \(78\)\(\medspace = 2 \cdot 3 \cdot 13 \)
Derived length:$3$

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

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)$$F_{13}\times C_3^2:\GL(2,3)$, of order \(67392\)\(\medspace = 2^{6} \cdot 3^{4} \cdot 13 \)
$\operatorname{Aut}(H)$ $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
