Subgroup ($H$) information

Description:$C_3^5$
Order: \(243\)\(\medspace = 3^{5} \)
Index: \(2\)
Exponent: \(3\)
Generators: $\left(\begin{array}{rr} 13 & 0 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 10 & 9 \\ 9 & 1 \end{array}\right), \left(\begin{array}{rr} 13 & 0 \\ 0 & 13 \end{array}\right), \left(\begin{array}{rr} 13 & 12 \\ 6 & 13 \end{array}\right), \left(\begin{array}{rr} 1 & 12 \\ 0 & 1 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the Fitting subgroup (hence characteristic, normal, nilpotent, solvable, supersolvable, and monomial), the socle, maximal, a semidirect factor, abelian (hence metabelian and an A-group), a $3$-Sylow subgroup (hence a Hall subgroup), and a $p$-group (hence elementary and hyperelementary).

Ambient group ($G$) information

Description: $S_3\times C_3^4$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Nilpotency class: $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, 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.\PSL(4,3).C_2\times S_3$, of order \(145566720\)\(\medspace = 2^{10} \cdot 3^{7} \cdot 5 \cdot 13 \)
$\operatorname{Aut}(H)$ $\GL(5,3)$, of order \(475566474240\)\(\medspace = 2^{10} \cdot 3^{10} \cdot 5 \cdot 11^{2} \cdot 13 \)
$\card{\operatorname{res}(\operatorname{Aut}(G))}$\(48522240\)\(\medspace = 2^{10} \cdot 3^{6} \cdot 5 \cdot 13 \)
