Subgroup ($H$) information

Description:$C_{11}$
Order: \(11\)
Index: \(162\)\(\medspace = 2 \cdot 3^{4} \)
Exponent: \(11\)
Generators: $d^{3}$ 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 $11$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.

Ambient group ($G$) information

Description: $C_3\times D_{11}\times \He_3$
Order: \(1782\)\(\medspace = 2 \cdot 3^{4} \cdot 11 \)
Exponent: \(66\)\(\medspace = 2 \cdot 3 \cdot 11 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_6\times \He_3$
Order: \(162\)\(\medspace = 2 \cdot 3^{4} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_3^4:(S_3\times \GL(2,3))$, of order \(23328\)\(\medspace = 2^{5} \cdot 3^{6} \)
Outer Automorphisms: $S_3\times C_3^2:\GL(2,3)$, of order \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
Nilpotency class: $2$
Derived length: $2$

The quotient is nonabelian, elementary for $p = 3$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), 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_3^4.Q_8.C_{33}.C_{30}.C_2^2$
$\operatorname{Aut}(H)$ $C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(256608\)\(\medspace = 2^{5} \cdot 3^{6} \cdot 11 \)
$W$$C_2$, of order \(2\)
