Subgroup ($H$) information

Description:$C_{220}$
Order: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Index: \(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Generators: $\left(\begin{array}{rrrr} 3 & 2 & 6 & 8 \\ 8 & 4 & 5 & 4 \\ 4 & 5 & 10 & 3 \\ 2 & 8 & 6 & 3 \end{array}\right), \left(\begin{array}{rrrr} 4 & 6 & 9 & 0 \\ 8 & 7 & 0 & 2 \\ 4 & 0 & 7 & 6 \\ 0 & 7 & 8 & 4 \end{array}\right), \left(\begin{array}{rrrr} 9 & 0 & 0 & 0 \\ 0 & 9 & 0 & 0 \\ 0 & 0 & 9 & 0 \\ 0 & 0 & 0 & 9 \end{array}\right), \left(\begin{array}{rrrr} 6 & 9 & 9 & 1 \\ 2 & 1 & 10 & 7 \\ 7 & 1 & 2 & 7 \\ 8 & 0 & 1 & 0 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5,11$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{15}:Q_8\times \SL(2,11)$
Order: \(158400\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5^{2} \cdot 11 \)
Exponent: \(660\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

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_2^5\times S_3).C_2^2.\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_2^2\times C_{20}$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \)
$W$$C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
