Subgroup ($H$) information
Description: | $D_5\times C_{15}$ |
Order: | \(150\)\(\medspace = 2 \cdot 3 \cdot 5^{2} \) |
Index: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
Exponent: | \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \) |
Generators: |
$ac^{9}d^{6}, c^{3}d^{6}, d^{3}, c^{10}$
|
Derived length: | $2$ |
The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.
Ambient group ($G$) information
Description: | $C_{15}^2:D_6$ |
Order: | \(2700\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 5^{2} \) |
Exponent: | \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \) |
Derived length: | $3$ |
The ambient group is nonabelian and monomial (hence solvable).
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_{15}^2.C_{12}.C_2^3$ |
$\operatorname{Aut}(H)$ | $C_{10}:C_4^2$, of order \(160\)\(\medspace = 2^{5} \cdot 5 \) |
$\operatorname{res}(S)$ | $C_2^2\times F_5$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(15\)\(\medspace = 3 \cdot 5 \) |
$W$ | $D_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \) |
