Subgroup ($H$) information

Description:$D_5\times A_4$
Order: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Index: \(32\)\(\medspace = 2^{5} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Generators: $\langle(6,7)(14,15), (1,5,3,2,4), (2,3)(4,5)(8,9)(12,13), (6,7)(10,11), (1,4,2,3,5)(6,10,14)(7,11,15)\rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2^3:F_5\times S_4$
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.

Quotient group ($Q$) structure

Description: $C_2^2\times D_4$
Order: \(32\)\(\medspace = 2^{5} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2^6:(C_2\times S_4)$, of order \(3072\)\(\medspace = 2^{10} \cdot 3 \)
Outer Automorphisms: $C_2^5:S_4$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \)
Derived length: $2$

The quotient is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metabelian, and rational.

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{res}(S)$$F_5\times S_4$, of order \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
