Subgroup ($H$) information

Description:$C_2\times A_4^2:D_6$
Order: \(3456\)\(\medspace = 2^{7} \cdot 3^{3} \)
Index: \(2\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(4,7)(5,6)(9,11)(10,13), (1,2)(5,7), (4,6)(5,7), (14,15), (1,2,3)(10,11,13) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, and solvable. Whether it is monomial has not been computed.

Ambient group ($G$) information

Description: $C_3:S_4\times \GL(2,\mathbb{Z}/4)$
Order: \(6912\)\(\medspace = 2^{8} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
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)$$C_2\times C_3.(C_3\times A_4^2).C_2^5$
$\operatorname{Aut}(H)$ $C_3:S_3:S_4\times S_4^2$
$W$$C_3:S_4^2$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
