Subgroup ($H$) information

Description:$D_4:F_{11}$
Order: \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \)
Index: \(2\)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Generators: $a^{5}, b^{2}, d, a^{2}, b^{11}, d^{2}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2\times D_4:F_{11}$
Order: \(1760\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, 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 $W = N_G(H) / Z_G(H)$.
