Subgroup ($H$) information

Description:$C_{17}$
Order: \(17\)
Index: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Exponent: \(17\)
Generators: $c^{3}$ 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 $17$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.

Ambient group ($G$) information

Description: $\He_3:D_{34}$
Order: \(1836\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 17 \)
Exponent: \(102\)\(\medspace = 2 \cdot 3 \cdot 17 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Quotient group ($Q$) structure

Description: $C_3^2:D_6$
Order: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_6.S_3^2$, of order \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Outer Automorphisms: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), 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_{51}.(C_{48}\times S_3).C_2$
$\operatorname{Aut}(H)$ $C_{16}$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_{16}$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(1836\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 17 \)
$W$$C_2$, of order \(2\)
