Subgroup ($H$) information

Description:$D_6^2$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(2,3)(6,7)(10,13)(11,16)(12,15)(14,18), (1,4)(2,3), (8,9), (10,17,13)(11,15,18)(12,16,14), (6,7)(8,9), (5,7,6)(10,13,17)(11,18,15)(12,14,16)\rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_6^3:S_3^2$
Order: \(7776\)\(\medspace = 2^{5} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
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_2\times C_6^2.C_3^4.C_2^4$
$\operatorname{Aut}(H)$ $D_6^2:(C_2\times S_4)$, of order \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
$W$$S_3\times D_6$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
