Subgroup ($H$) information

Description:$C_6:C_{56}$
Order: \(336\)\(\medspace = 2^{4} \cdot 3 \cdot 7 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Generators: $bc^{7}, d^{4}, c^{4}, c^{14}d^{3}, d^{3}, d^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.

Ambient group ($G$) information

Description: $(C_3\times D_{14}):Q_{16}$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
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 \(6\)\(\medspace = 2 \cdot 3 \)
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 $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{42}.(C_2^5\times C_6).C_2^3$
$\operatorname{Aut}(H)$ $C_6^2:C_2^4$, of order \(576\)\(\medspace = 2^{6} \cdot 3^{2} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_6^2:C_2^3$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(224\)\(\medspace = 2^{5} \cdot 7 \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
