Subgroup ($H$) information
Description: | $C_4^2\times C_8$ |
Order: | \(128\)\(\medspace = 2^{7} \) |
Index: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Exponent: | \(8\)\(\medspace = 2^{3} \) |
Generators: |
$\left(\begin{array}{rr}
21 & 0 \\
0 & 21
\end{array}\right), \left(\begin{array}{rr}
9 & 8 \\
16 & 25
\end{array}\right), \left(\begin{array}{rr}

Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and a $p$-group (hence elementary and hyperelementary).
Ambient group ($G$) information
Description: | $C_4^4.C_{24}$ |
Order: | \(6144\)\(\medspace = 2^{11} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $2$ |
The ambient group is nonabelian and metabelian (hence solvable). Whether it is monomial has not been computed.
Quotient group ($Q$) structure
Description: | $C_2^2\times C_{12}$ |
Order: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Exponent: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Automorphism Group: | $C_2^4:S_4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \) |
Outer Automorphisms: | $C_2^4:S_4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and elementary for $p = 2$ (hence hyperelementary).
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_4^2.(C_2^4\times C_{12}).C_2^6.C_2^3$ |
$\operatorname{Aut}(H)$ | $C_2^8.C_4^2:S_4$, of order \(98304\)\(\medspace = 2^{15} \cdot 3 \) |
$W$ | $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
