Subgroup ($H$) information

Description:$C_{36}$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(5402\)\(\medspace = 2 \cdot 37 \cdot 73 \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Generators: $\left[ \left(\begin{array}{rr} 10 & 37 \\ 6 & 15 \end{array}\right) \right], \left[ \left(\begin{array}{rr} 63 & 53 \\ 52 & 9 \end{array}\right) \right], \left[ \left(\begin{array}{rr} 27 & 27 \\ 32 & 5 \end{array}\right) \right], \left[ \left(\begin{array}{rr} 60 & 61 \\ 2 & 13 \end{array}\right) \right]$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $\PSL(2,73)$
Order: \(194472\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 37 \cdot 73 \)
Exponent: \(97236\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 37 \cdot 73 \)
Derived length:$0$

The ambient group is nonabelian and simple (hence nonsolvable, perfect, quasisimple, and almost simple).

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)$$\PGL(2,73)$, of order \(388944\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 37 \cdot 73 \)
$\operatorname{Aut}(H)$ $C_2\times C_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$W$$C_2$, of order \(2\)
