Subgroup ($H$) information

Description:$C_2\times C_{18}$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $b^{18}c^{6}, c^{6}, b^{4}, b^{12}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), central (hence abelian, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (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: $C_4\times D_6$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^4:D_6$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
Outer Automorphisms: $C_2^2\wr C_2$, of order \(32\)\(\medspace = 2^{5} \)
Nilpotency class: $-1$
Derived length: $2$

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

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$
$\operatorname{Aut}(H)$ $C_6\times S_3$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
$\card{W}$$1$
