Subgroup ($H$) information

Description:$C_2^2$

Index: \(39600\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5^{2} \cdot 11 \)
Exponent: \(2\)
Generators: $\left(\begin{array}{rrrr} 4 & 6 & 9 & 0 \\ 8 & 7 & 0 & 2 \\ 4 & 0 & 7 & 6 \\ 0 & 7 & 8 & 4 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the Frattini subgroup (hence characteristic and normal), stem (hence abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.

Ambient group ($G$) information

Description: $C_{15}:Q_8\times \SL(2,11)$

Exponent: \(660\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$(C_2^5\times S_3).C_2^2.\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_1$, of order $1$
