Subgroup ($H$) information

Description:$C_3$
Order: \(3\)
Index: \(224\)\(\medspace = 2^{5} \cdot 7 \)
Exponent: \(3\)
Generators: $c^{56}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $3$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.

Ambient group ($G$) information

Description: $C_{24}.D_{14}$
Order: \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
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.

Quotient group ($Q$) structure

Description: $C_4.D_{28}$
Order: \(224\)\(\medspace = 2^{5} \cdot 7 \)
Exponent: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Automorphism Group: $F_7\times D_4^2$, of order \(2688\)\(\medspace = 2^{7} \cdot 3 \cdot 7 \)
Outer Automorphisms: $C_2^2\times C_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

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)$
$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
