Subgroup ($H$) information

Description:$D_{30}:C_2^3$
Order: \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $\langle(1,3)(4,5)(6,10,7,11)(12,15)(13,14), (1,4)(2,3)(8,14,13)(9,15,12)(10,11) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Ambient group ($G$) information

Description: $C_2\times \GL(2,\mathbb{Z}/4):F_5$
Order: \(3840\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
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)$$(C_5\times A_4).C_2^4.C_2^6$
$\operatorname{Aut}(H)$ $C_{15}:(C_2^4.C_2^6)$
$\operatorname{res}(S)$$C_2^4:D_6\times F_5$, of order \(3840\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$D_6\times F_5$, of order \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
