Subgroup ($H$) information

Description:$C_6\times D_{28}$
Order: \(336\)\(\medspace = 2^{4} \cdot 3 \cdot 7 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Generators: $a, c^{8}, c^{14}d^{3}, d^{2}, b, c^{28}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $D_{84}:C_2^3$
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.

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_{42}.(C_2^5\times C_6).C_2^5$
$\operatorname{Aut}(H)$ $C_2^4:D_4\times F_7$, of order \(5376\)\(\medspace = 2^{8} \cdot 3 \cdot 7 \)
$\card{W}$\(28\)\(\medspace = 2^{2} \cdot 7 \)
