Subgroup ($H$) information

Description:$C_3^4:S_3$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a^{4}, f, e, bc^{2}f, c, de$ Copy content Toggle raw display
Derived length: $3$

The subgroup is characteristic (hence normal), nonabelian, and supersolvable (hence solvable and monomial).

Ambient group ($G$) information

Description: $\He_3:F_9$
Order: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Quotient group ($Q$) structure

Description: $C_4$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Derived length: $1$

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

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_3^2\times \He_3).C_8^2.C_2$, of order \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_3^6.(C_3^2:\GL(2,3)\times \GL(2,3))$, of order \(15116544\)\(\medspace = 2^{8} \cdot 3^{10} \)
$\card{\operatorname{res}(\operatorname{Aut}(G))}$\(10368\)\(\medspace = 2^{7} \cdot 3^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3\)
