Subgroup ($H$) information

Description:$C_{14}:Q_{16}$
Order: \(224\)\(\medspace = 2^{5} \cdot 7 \)
Index: \(2\)
Exponent: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Generators: $a, c^{16}, c^{98}, c^{28}, b, c^{56}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{14}:Q_{32}$
Order: \(448\)\(\medspace = 2^{6} \cdot 7 \)
Exponent: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
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

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{28}.(C_2^4\times C_6).C_2^4$
$\operatorname{Aut}(H)$ $C_{28}.(C_6\times D_4^2)$, of order \(10752\)\(\medspace = 2^{9} \cdot 3 \cdot 7 \)
$\card{\operatorname{res}(S)}$\(5376\)\(\medspace = 2^{8} \cdot 3 \cdot 7 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$D_{56}$, of order \(112\)\(\medspace = 2^{4} \cdot 7 \)
