Subgroup ($H$) information

Description:$C_{12}:D_{28}$
Order: \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
Index: \(2\)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Generators: $a, d^{28}, c, c^{2}, b, d^{12}, d^{42}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_{12}\times D_{28}):C_2$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
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: $C_2$
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_2^6.(D_4\times D_6)$, of order \(129024\)\(\medspace = 2^{11} \cdot 3^{2} \cdot 7 \)
$\operatorname{Aut}(H)$ $C_2^6\times S_3\times F_7$
$\card{W}$\(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
