Subgroup ($H$) information
Description: | $C_{12}^2.C_2$ |
Order: | \(288\)\(\medspace = 2^{5} \cdot 3^{2} \) |
Index: | \(6\)\(\medspace = 2 \cdot 3 \) |
Exponent: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Generators: |
$b^{3}, b^{6}, b^{4}, a^{6}, c^{6}, c^{3}, c^{4}$

Nilpotency class: | $2$ |
Derived length: | $2$ |
The subgroup is normal, nonabelian, nilpotent (hence solvable, supersolvable, and monomial), and metabelian.
Ambient group ($G$) information
Description: | $C_4.D_8\times \He_3$ |
Order: | \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \) |
Exponent: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Nilpotency class: | $3$ |
Derived length: | $2$ |
The ambient group is nonabelian, nilpotent (hence solvable, supersolvable, and monomial), and metabelian.
Quotient group ($Q$) structure
Description: | $C_6$ |
Order: | \(6\)\(\medspace = 2 \cdot 3 \) |
Exponent: | \(6\)\(\medspace = 2 \cdot 3 \) |
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 ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^2\times D_4^2\times \AGL(2,3)$ |
$\operatorname{Aut}(H)$ | $C_2^4.C_2^3.C_2^2\times \GL(2,3)$ |
$\operatorname{res}(S)$ | $D_6\times D_4^2$, of order \(768\)\(\medspace = 2^{8} \cdot 3 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(36\)\(\medspace = 2^{2} \cdot 3^{2} \) |
$W$ | $C_2^2:C_{12}$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \) |
