Subgroup ($H$) information

Description:$C_2^2\times C_4$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(1512\)\(\medspace = 2^{3} \cdot 3^{3} \cdot 7 \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $\langle(1,2), (1,2)(3,5,6,4)(7,12)(8,10)(9,15)(13,14), (3,6)(4,5), (7,8)(9,13)(10,12)(14,15)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and a $p$-group (hence elementary and hyperelementary).

Ambient group ($G$) information

Description: $D_4\times \SL(2,8):C_6$
Order: \(24192\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 7 \)
Exponent: \(252\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 7 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

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)$$\SL(2,8).C_3\times C_2\wr C_2^2$, of order \(96768\)\(\medspace = 2^{9} \cdot 3^{3} \cdot 7 \)
$\operatorname{Aut}(H)$ $C_2^3:S_4$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
$W$$C_2$, of order \(2\)
