Order: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\left(\begin{array}{rrrr} 1 & 2 & 1 & 1 \\ 0 & 2 & 0 & 0 \\ 2 & 0 & 2 & 0 \\ 1 & 1 & 2 & 1 \end{array}\right), \left(\begin{array}{rrrr} 0 & 2 & 0 & 1 \\ 0 & 1 & 1 & 1 \\ 1 & 0 & 1 & 0 \\ 2 & 2 & 2 & 0 \end{array}\right), \left(\begin{array}{rrrr} 2 & 0 & 2 & 0 \\ 0 & 1 & 0 & 0 \\ 1 & 0 & 0 & 0 \\ 2 & 0 & 1 & 1 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 0 & 2 & 0 & 0 \\ 2 & 0 & 2 & 0 \\ 1 & 0 & 0 & 2 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 1 & 0 & 0 & 1 \\ 2 & 0 & 2 & 0 \\ 2 & 1 & 0 & 0 \end{array}\right), \left(\begin{array}{rrrr} 2 & 2 & 0 & 1 \\ 0 & 0 & 1 & 1 \\ 1 & 0 & 0 & 0 \\ 2 & 2 & 2 & 2 \end{array}\right), \left(\begin{array}{rrrr} 0 & 2 & 2 & 1 \\ 0 & 1 & 0 & 0 \\ 2 & 2 & 0 & 1 \\ 1 & 1 & 1 & 0 \end{array}\right)$ Copy content Toggle raw display
Derived length: $3$

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

Ambient group ($G$) information

Description: $C_6^2:\GL(2,3)$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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)$$S_4\times C_3^2:\GL(2,3)$, of order \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \)
$\operatorname{Aut}(H)$ $(C_2^4\times \He_3).D_6.C_2^2$
$\operatorname{res}(S)$$C_3^2:D_6\times S_4$, of order \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$$1$
$W$$C_3^2:D_6$, of order \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
