Subgroup ($H$) information

Description:$C_{10}$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Index: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\langle(1,5,3,2,4), (8,9)(12,13)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_2^3:F_5\times S_4$
Order: \(3840\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_2^5.D_6$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^6.C_2^4.S_3^2$
Outer Automorphisms: $C_2^6:S_4$, of order \(1536\)\(\medspace = 2^{9} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian and monomial (hence solvable).

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 $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$(C_5\times A_4).C_2^6.C_2^5$
$\operatorname{Aut}(H)$ $C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(30720\)\(\medspace = 2^{11} \cdot 3 \cdot 5 \)
$W$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
