Subgroup ($H$) information

Description:$C_3\times C_{18}$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Index: \(32\)\(\medspace = 2^{5} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $b^{18}, b^{4}, c^{4}, b^{12}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 3$ (hence hyperelementary), and metacyclic.

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: $C_4^2:C_2$
Order: \(32\)\(\medspace = 2^{5} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2^5:D_4$, of order \(256\)\(\medspace = 2^{8} \)
Outer Automorphisms: $D_4^2$, of order \(64\)\(\medspace = 2^{6} \)
Nilpotency class: $2$
Derived length: $2$

The quotient is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

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$
$\operatorname{Aut}(H)$ $C_3^2:D_6$, of order \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
$\card{W}$\(2\)
