Subgroup ($H$) information

Description:$(C_2\times C_{12}):C_{36}$
Order: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Index: \(2\)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Generators: $ab^{9}, b^{18}, c^{6}, c^{3}, a^{2}c^{6}, c^{4}, b^{12}, b^{4}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), maximal, nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Ambient group ($G$) information

Description: $C_2^2.(D_6\times C_{36})$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.

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_6.(C_2^5\times C_6).C_2^5$
$\operatorname{Aut}(H)$ $(C_2\times C_6^2).C_2^6$
$\card{W}$\(24\)\(\medspace = 2^{3} \cdot 3 \)
