Subgroup ($H$) information
Description: | $C_2^3:C_{16}$ |
Order: | \(128\)\(\medspace = 2^{7} \) |
Index: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Exponent: | \(16\)\(\medspace = 2^{4} \) |
Generators: |
$\left(\begin{array}{rr}
30 & 31 \\
1 & 18
\end{array}\right), \left(\begin{array}{rr}
31 & 0 \\
0 & 31
\end{array}\right), \left(\begin{array}{rr}
17 & 0 \\
16 & 17
\end{array}\right)$

Nilpotency class: | $2$ |
Derived length: | $2$ |
The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.
Ambient group ($G$) information
Description: | $(C_4\times C_8).\GL(2,\mathbb{Z}/4)$ |
Order: | \(3072\)\(\medspace = 2^{10} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $3$ |
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $(C_4\times A_4).C_2^5.C_2^6$ |
$\operatorname{Aut}(H)$ | $C_2^5.C_2^6$, of order \(2048\)\(\medspace = 2^{11} \) |
$\card{W}$ | \(8\)\(\medspace = 2^{3} \) |
