Subgroup ($H$) information

Description:$C_{60}$
Order: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Index: \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $\left(\begin{array}{rrrr} 9 & 9 & 8 & 10 \\ 3 & 8 & 0 & 8 \\ 6 & 5 & 3 & 2 \\ 6 & 6 & 8 & 2 \end{array}\right), \left(\begin{array}{rrrr} 9 & 0 & 0 & 0 \\ 0 & 9 & 0 & 0 \\ 0 & 0 & 9 & 0 \\ 0 & 0 & 0 & 9 \end{array}\right), \left(\begin{array}{rrrr} 2 & 8 & 1 & 4 \\ 10 & 6 & 0 & 1 \\ 9 & 2 & 4 & 3 \\ 9 & 9 & 1 & 8 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the Fitting subgroup (hence characteristic, normal, nilpotent, solvable, supersolvable, and monomial) and cyclic (hence abelian, elementary ($p = 2,3,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_5\times \SL(2,11):D_6$
Order: \(79200\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5^{2} \cdot 11 \)
Exponent: \(660\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

Quotient group ($Q$) structure

Description: $C_2\times \PSL(2,11)$
Order: \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Exponent: \(330\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 11 \)
Automorphism Group: $\PGL(2,11)$, of order \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $-1$
Derived length: $1$

The quotient is nonabelian, an A-group, and nonsolvable.

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)$$(C_4\times S_3\times D_4).\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_2^2\times C_4$, of order \(16\)\(\medspace = 2^{4} \)
$W$$C_2$, of order \(2\)
