Subgroup ($H$) information

Description:$D_5\times C_5^2$
Order: \(250\)\(\medspace = 2 \cdot 5^{3} \)
Index: \(81\)\(\medspace = 3^{4} \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $a^{15}, d^{3}, c^{3}d^{12}, a^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, a Hall subgroup, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_{15}\wr S_3$
Order: \(20250\)\(\medspace = 2 \cdot 3^{4} \cdot 5^{3} \)
Exponent: \(90\)\(\medspace = 2 \cdot 3^{2} \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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_6^2.C_2^4$
$\operatorname{Aut}(H)$ $F_5\times \GL(2,5)$, of order \(9600\)\(\medspace = 2^{7} \cdot 3 \cdot 5^{2} \)
$W$$D_5$, of order \(10\)\(\medspace = 2 \cdot 5 \)
