Subgroup ($H$) information

Description:$C_5$
Order: \(5\)
Index: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Exponent: \(5\)
Generators: $bc^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_5^3:C_4$
Order: \(500\)\(\medspace = 2^{2} \cdot 5^{3} \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Quotient group ($Q$) structure

Description: $C_5:F_5$
Order: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Automorphism Group: $F_5^2$, of order \(400\)\(\medspace = 2^{4} \cdot 5^{2} \)
Outer Automorphisms: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

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_5^2:C_4.S_5\times F_5$, of order \(240000\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{4} \)
$\operatorname{Aut}(H)$ $C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\operatorname{res}(S)$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(10000\)\(\medspace = 2^{4} \cdot 5^{4} \)
