Subgroup ($H$) information

Description:$C_{11}$
Order: \(11\)
Index: \(1210\)\(\medspace = 2 \cdot 5 \cdot 11^{2} \)
Exponent: \(11\)
Generators: $d$ Copy content Toggle raw display
Nilpotency class: $1$

The subgroup is the Frattini subgroup (hence characteristic and normal), the socle, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, and simple.

Ambient group ($G$) information

Description: $C_{11}^2:F_{11}$
Order: \(13310\)\(\medspace = 2 \cdot 5 \cdot 11^{3} \)
Exponent: \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_{11}:F_{11}$
Order: \(1210\)\(\medspace = 2 \cdot 5 \cdot 11^{2} \)
Exponent: \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \)
Automorphism Group: $C_{11}^2.\GL(2,11)$, of order \(1597200\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 11^{3} \)
Outer Automorphisms: $\PGL(2,11)$, of order \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Nilpotency class: $-1$
Derived length: $2$

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

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$\He_{11}.C_{10}.\PSL(2,11).C_2$, of order \(17569200\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 11^{4} \)
$\operatorname{Aut}(H)$ $C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$W$$C_5$, of order \(5\)
