Subgroup ($H$) information

Description:$C_{12}:D_6$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(8,13)(10,11), (7,11,14,10)(8,9,13,12), (1,5)(2,6)(8,13)(9,12), (1,3,5)(2,6,4), (7,14)(8,13)(9,12)(10,11), (2,6,4)\rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), metabelian, and rational.

Ambient group ($G$) information

Description: $D_6^2:C_2^2:A_4$
Order: \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

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_6^2.(C_4\times A_4).C_2^5.C_2$
$\operatorname{Aut}(H)$ $C_2\times C_2^4.\SL(3,3)$, of order \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
$W$$C_2\times C_6^2:C_4$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
