Subgroup ($H$) information

Description:$C_2\times C_{12}$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $b^{2}, c, d^{14}, c^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $(C_2\times C_{12}):D_{28}$
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: $C_2\times D_{14}$
Order: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Exponent: \(14\)\(\medspace = 2 \cdot 7 \)
Automorphism Group: $S_4\times F_7$, of order \(1008\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 7 \)
Outer Automorphisms: $C_3\times S_4$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Nilpotency class: $-1$
Derived length: $2$

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

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_2^5$
$\operatorname{Aut}(H)$ $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
$\card{W}$\(2\)
