Subgroup ($H$) information

Description:$C_{44}:F_{11}$
Order: \(4840\)\(\medspace = 2^{3} \cdot 5 \cdot 11^{2} \)
Index: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Generators: $a^{5}, c^{20}, a^{2}c^{16}, c^{110}, c^{55}, b^{2}c^{198}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{55}:(Q_8\times F_{11})$
Order: \(48400\)\(\medspace = 2^{4} \cdot 5^{2} \cdot 11^{2} \)
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: $C_{10}$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Outer Automorphisms: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

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)$$C_{11}^2.C_{10}^2.C_{10}.C_2^6$
$\operatorname{Aut}(H)$ $C_2^2\times C_{11}^2.C_{10}.\PSL(2,11).C_2$
$W$$D_{11}:F_{11}$, of order \(2420\)\(\medspace = 2^{2} \cdot 5 \cdot 11^{2} \)
