| Derived length: | $3$ |
The subgroup is maximal, nonabelian, monomial (hence solvable), and an A-group.
Ambient group ($G$) information
| Description: | $\POMinus(4,5)$ |
| Order: | \(15600\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 13 \) |
| Exponent: | \(780\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 13 \) |
| Derived length: | $1$ |
The ambient group is nonabelian, almost simple, and nonsolvable.
Quotient set structure
Since this subgroup has trivial core, the ambient group $G$ acts faithfully and transitively on the set of cosets of $H$. The resulting permutation representation is isomorphic to 26T57.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $\PSL(2,25).C_2^2$, of order \(31200\)\(\medspace = 2^{5} \cdot 3 \cdot 5^{2} \cdot 13 \) |
| $\operatorname{Aut}(H)$ | $F_{25}:C_2$, of order \(1200\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \) |
| $W$ | $C_5^2:(C_4\times S_3)$, of order \(600\)\(\medspace = 2^{3} \cdot 3 \cdot 5^{2} \) |
