Subgroup ($H$) information

Description:$C_5\times \SL(2,3)$
Order: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $c^{2}, d, e^{15}, e^{4}, e^{10}$ Copy content Toggle raw display
Derived length: $3$

The subgroup is the commutator subgroup (hence characteristic and normal), a semidirect factor, nonabelian, and solvable.

Ambient group ($G$) information

Description: $\GL(2,3):D_{10}$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$4$

The ambient group is nonabelian and solvable.

Quotient group ($Q$) structure

Description: $C_2^3$
Order: \(8\)\(\medspace = 2^{3} \)
Exponent: \(2\)
Automorphism Group: $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Outer Automorphisms: $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Derived length: $1$

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

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_2^2\times D_5\times A_4).C_2^5$
$\operatorname{Aut}(H)$ $C_4\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\card{W}$\(48\)\(\medspace = 2^{4} \cdot 3 \)
