Subgroup ($H$) information
| Description: | $C_{55}$ |
| Order: | \(55\)\(\medspace = 5 \cdot 11 \) |
| Index: | \(726\)\(\medspace = 2 \cdot 3 \cdot 11^{2} \) |
| Exponent: | \(55\)\(\medspace = 5 \cdot 11 \) |
| Generators: |
$\left(\begin{array}{rr}
81 & 0 \\
0 & 81
\end{array}\right), \left(\begin{array}{rr}
89 & 0 \\
0 & 89
\end{array}\right)$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is the center (hence characteristic, normal, abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a direct factor, and cyclic (hence elementary ($p = 5,11$), hyperelementary, metacyclic, and a Z-group).
Ambient group ($G$) information
| Description: | $C_5\times C_{11}\wr S_3$ |
| Order: | \(39930\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 11^{3} \) |
| Exponent: | \(330\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 11 \) |
| Derived length: | $3$ |
The ambient group is nonabelian, monomial (hence solvable), and an A-group.
Quotient group ($Q$) structure
| Description: | $C_{11}^2:S_3$ |
| Order: | \(726\)\(\medspace = 2 \cdot 3 \cdot 11^{2} \) |
| Exponent: | \(66\)\(\medspace = 2 \cdot 3 \cdot 11 \) |
| Automorphism Group: | $C_{11}^2:(S_3\times C_{10})$, of order \(7260\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11^{2} \) |
| Outer Automorphisms: | $C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \) |
| Nilpotency class: | $-1$ |
| Derived length: | $3$ |
The quotient is nonabelian, monomial (hence solvable), and an A-group.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{11}^2.C_{15}.C_{10}.C_2^4$ |
| $\operatorname{Aut}(H)$ | $C_2\times C_{20}$, of order \(40\)\(\medspace = 2^{3} \cdot 5 \) |
| $W$ | $C_1$, of order $1$ |
