Subgroup ($H$) information

Description:$C_4.C_2^3$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(150\)\(\medspace = 2 \cdot 3 \cdot 5^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $\left(\begin{array}{rrrr} 6 & 9 & 5 & 9 \\ 0 & 6 & 0 & 5 \\ 8 & 8 & 5 & 2 \\ 0 & 8 & 0 & 5 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 3 & 8 & 2 & 0 \\ 3 & 7 & 3 & 0 \\ 5 & 3 & 8 & 10 \end{array}\right), \left(\begin{array}{rrrr} 9 & 3 & 3 & 6 \\ 4 & 8 & 7 & 3 \\ 10 & 7 & 3 & 8 \\ 9 & 10 & 7 & 2 \end{array}\right), \left(\begin{array}{rrrr} 7 & 4 & 7 & 0 \\ 6 & 0 & 7 & 7 \\ 2 & 7 & 0 & 7 \\ 3 & 2 & 5 & 4 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_5\times \GL(2,3):D_{10}$
Order: \(4800\)\(\medspace = 2^{6} \cdot 3 \cdot 5^{2} \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$4$

The ambient group is nonabelian and solvable.

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_2\times A_4\times F_5).C_2^5$
$\operatorname{Aut}(H)$ $C_2^4:S_5$, of order \(1920\)\(\medspace = 2^{7} \cdot 3 \cdot 5 \)
$\operatorname{res}(S)$$C_2^2\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(32\)\(\medspace = 2^{5} \)
$W$$C_2^2\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
