Subgroup ($H$) information

Description:$D_4\times D_{10}$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $\langle(1,3)(4,5)(6,10,7,11)(12,15)(13,14), (6,7)(10,11), (2,5)(3,4)(12,13)(14,15), (2,5)(3,4)(10,11), (6,7)(8,9), (1,3,5,2,4)\rangle$ 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$
$\operatorname{Aut}(H)$ $F_5\times C_2^5:D_4$, of order \(5120\)\(\medspace = 2^{10} \cdot 5 \)
$\operatorname{res}(S)$$C_2^2\wr C_2\times F_5$, of order \(640\)\(\medspace = 2^{7} \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$C_2^2\times F_5$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \)
