Subgroup ($H$) information

Description:$C_2\times S_4$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(80\)\(\medspace = 2^{4} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(6,7)(14,15), (6,7)(10,11), (6,14,7,15)(8,9)(12,13), (6,7)(8,9)(10,11)(12,13)(14,15), (6,10,14)(7,11,15)\rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is normal, a direct factor, nonabelian, monomial (hence solvable), and rational.

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: $D_{10}:C_4$
Order: \(80\)\(\medspace = 2^{4} \cdot 5 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Automorphism Group: $D_4\times F_5$, of order \(160\)\(\medspace = 2^{5} \cdot 5 \)
Outer Automorphisms: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Derived length: $2$

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

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_2^6.C_2^5$
$\operatorname{Aut}(H)$ $C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(640\)\(\medspace = 2^{7} \cdot 5 \)
$W$$S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
