Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(772\)\(\medspace = 2^{2} \cdot 193 \)
Exponent: \(2\)
Generators: $a^{2}b^{193}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $p$-group, simple, and rational.

Ambient group ($G$) information

Description: $C_{386}:C_4$
Order: \(1544\)\(\medspace = 2^{3} \cdot 193 \)
Exponent: \(772\)\(\medspace = 2^{2} \cdot 193 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_{193}:C_4$
Order: \(772\)\(\medspace = 2^{2} \cdot 193 \)
Exponent: \(772\)\(\medspace = 2^{2} \cdot 193 \)
Automorphism Group: $C_2\times F_{193}$, of order \(74112\)\(\medspace = 2^{7} \cdot 3 \cdot 193 \)
Outer Automorphisms: $C_2\times C_{96}$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

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_{386}.C_{96}.C_2^3$
$\operatorname{Aut}(H)$ $C_1$, of order $1$
