Subgroup ($H$) information
| Description: | $C_{11}^2:C_5^2$ |
| Order: | \(3025\)\(\medspace = 5^{2} \cdot 11^{2} \) |
| Index: | \(4\)\(\medspace = 2^{2} \) |
| Exponent: | \(55\)\(\medspace = 5 \cdot 11 \) |
| Generators: |
$a^{2}, b^{10}, c, b^{22}$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), a semidirect factor, nonabelian, a Hall subgroup, supersolvable (hence solvable and monomial), metabelian, and an A-group.
Ambient group ($G$) information
| Description: | $C_{11}^2:C_{10}^2$ |
| Order: | \(12100\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 11^{2} \) |
| Exponent: | \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.
Quotient group ($Q$) structure
| Description: | $C_2^2$ |
| Order: | \(4\)\(\medspace = 2^{2} \) |
| Exponent: | \(2\) |
| Automorphism Group: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| Outer Automorphisms: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $F_{11}^2:C_2^2$, of order \(48400\)\(\medspace = 2^{4} \cdot 5^{2} \cdot 11^{2} \) |
| $\operatorname{Aut}(H)$ | $F_{11}\wr C_2$, of order \(24200\)\(\medspace = 2^{3} \cdot 5^{2} \cdot 11^{2} \) |
| $W$ | $C_{11}:(C_5\times F_{11})$, of order \(6050\)\(\medspace = 2 \cdot 5^{2} \cdot 11^{2} \) |
