Subgroup ($H$) information

Description:not computed
Order: \(1562500\)\(\medspace = 2^{2} \cdot 5^{8} \)
Index: \(256\)\(\medspace = 2^{8} \)
Exponent: not computed
Generators: $\langle(2,5)(3,4)(6,7)(8,10)(12,15)(13,14)(16,20)(17,19)(21,24)(22,23)(27,30)(28,29) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: not computed

The subgroup is characteristic (hence normal), nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group. Whether it is a direct factor, a semidirect factor, elementary, hyperelementary, monomial, simple, quasisimple, perfect, almost simple, or rational has not been computed.

Ambient group ($G$) information

Description: $C_5^4.D_5^4.C_2^3:C_8$
Order: \(400000000\)\(\medspace = 2^{10} \cdot 5^{8} \)
Exponent: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Derived length:$4$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Quotient group ($Q$) structure

Description: $C_2^4.(C_2\times D_4)$
Order: \(256\)\(\medspace = 2^{8} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Automorphism Group: $C_2^7.D_4^2$, of order \(8192\)\(\medspace = 2^{13} \)
Outer Automorphisms: $C_2\times D_4^2$, of order \(128\)\(\medspace = 2^{7} \)
Derived length: $2$

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

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 $W = G / Z_G(H)$.
