Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Exponent: \(2\)
Generators: $a^{4}b^{15}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_{10}:C_{24}$
Order: \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.

Quotient group ($Q$) structure

Description: $C_5:C_{24}$
Order: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Automorphism Group: $C_2^3\times F_5$, of order \(160\)\(\medspace = 2^{5} \cdot 5 \)
Outer Automorphisms: $C_2^4$, of order \(16\)\(\medspace = 2^{4} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.

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)$$D_{10}.C_2^5$, of order \(640\)\(\medspace = 2^{7} \cdot 5 \)
$\operatorname{Aut}(H)$ $C_1$, of order $1$
$\operatorname{res}(S)$$C_1$, of order $1$
$\card{\operatorname{ker}(\operatorname{res})}$\(320\)\(\medspace = 2^{6} \cdot 5 \)
$W$$C_1$, of order $1$
