Subgroup ($H$) information

Description:$C_2^3\times F_5$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $\left(\begin{array}{rr} 13 & 10 \\ 0 & 19 \end{array}\right), \left(\begin{array}{rr} 1 & 8 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 11 & 10 \\ 0 & 11 \end{array}\right), \left(\begin{array}{rr} 1 & 10 \\ 10 & 1 \end{array}\right), \left(\begin{array}{rr} 11 & 0 \\ 0 & 11 \end{array}\right), \left(\begin{array}{rr} 9 & 0 \\ 0 & 1 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2\times F_5\times \GL(2,\mathbb{Z}/4)$
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: $C_2\times D_6$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Outer Automorphisms: $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, an A-group, 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{Aut}(G)$$(C_5\times A_4).C_2^4.C_2^6$
$\operatorname{Aut}(H)$ $F_5\times C_2^3:\GL(3,2)$, of order \(26880\)\(\medspace = 2^{8} \cdot 3 \cdot 5 \cdot 7 \)
$\operatorname{res}(S)$$D_6\times F_5$, of order \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(128\)\(\medspace = 2^{7} \)
$W$$S_3\times F_5$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
