Subgroup ($H$) information
Description: | $C_5:S_4$ |
Order: | \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \) |
Index: | \(5\) |
Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
Generators: |
$a, c^{2}d^{4}, c^{5}d^{5}, b, d^{5}$
|
Derived length: | $3$ |
The subgroup is maximal, nonabelian, and monomial (hence solvable).
Ambient group ($G$) information
Description: | $C_5^2:S_4$ |
Order: | \(600\)\(\medspace = 2^{3} \cdot 3 \cdot 5^{2} \) |
Exponent: | \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \) |
Derived length: | $3$ |
The ambient group is nonabelian and monomial (hence 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $(S_4\times C_5^2):\GL(2,5)$, of order \(288000\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 5^{3} \) |
$\operatorname{Aut}(H)$ | $F_5\times S_4$, of order \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \) |
$\operatorname{res}(S)$ | $F_5\times S_4$, of order \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(20\)\(\medspace = 2^{2} \cdot 5 \) |
$W$ | $C_5:S_4$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \) |
