Subgroup ($H$) information

Description:$C_{14}:Q_8$
Order: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Generators: $a, c^{42}, c^{84}, b^{2}c^{84}, c^{24}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_6.(C_4\times D_{28})$
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: $D_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Outer Automorphisms: $C_2$, of order \(2\)
Derived length: $2$

The quotient is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, an A-group, 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$
$\operatorname{Aut}(H)$ $C_2\wr C_2^2\times F_7$, of order \(2688\)\(\medspace = 2^{7} \cdot 3 \cdot 7 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times D_4\times F_7$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$D_{28}$, of order \(56\)\(\medspace = 2^{3} \cdot 7 \)
