Subgroup ($H$) information

Description:$C_6.C_4^2$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $acd^{3}, d^{6}, c^{2}d^{6}, b, d^{4}, b^{2}d^{6}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is characteristic (hence normal), nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $(C_2\times C_4^2).D_6$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(2\)
Automorphism Group: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Outer Automorphisms: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, 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 $W = G / Z_G(H)$.
