Subgroup ($H$) information

Description:$C_3^3:A_4^2$
Order: \(3888\)\(\medspace = 2^{4} \cdot 3^{5} \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $\langle(7,12,15,8,11,13,9,10,14), (10,12,11), (7,8)(13,15), (1,2)(3,4)(11,12)(13,15) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

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

Ambient group ($G$) information

Description: $C_2\times C_3^3:S_4^2$
Order: \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$4$

The ambient group is nonabelian and monomial (hence 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\times C_3^3.A_4^2.C_2^4$
$\operatorname{Aut}(H)$ $S_3\wr S_3\times S_4$, of order \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
$W$$C_3^3:S_4^2$, of order \(15552\)\(\medspace = 2^{6} \cdot 3^{5} \)
