Subgroup ($H$) information

Description:$C_{14}$
Order: \(14\)\(\medspace = 2 \cdot 7 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(14\)\(\medspace = 2 \cdot 7 \)
Generators: $d^{42}, d^{12}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,7$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $D_{12}:D_{14}$
Order: \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2^2\times D_6$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $S_3\times C_2^3:\GL(3,2)$, of order \(8064\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 7 \)
Outer Automorphisms: $C_2^3:\GL(3,2)$, of order \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, 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$
$\operatorname{Aut}(H)$ $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(10752\)\(\medspace = 2^{9} \cdot 3 \cdot 7 \)
$W$$C_2$, of order \(2\)
