Subgroup ($H$) information

Description:$C_4\times C_{60}$
Order: \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $ac^{15}, c^{30}, c^{40}, c^{12}, b^{6}c^{15}, b^{4}c^{30}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_2\times C_{12}:C_{40}$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_4$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group) and a $p$-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_3:(C_2^2\times C_4\times C_2^6.C_2^3)$
$\operatorname{Aut}(H)$ $C_2^6.D_6$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \)
$\operatorname{res}(S)$$C_2^5\times C_4$, of order \(128\)\(\medspace = 2^{7} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$C_2$, of order \(2\)
