Template:Dynkin/testcases

This is the template test cases page for the sandbox of Template:Dynkin. Purge this page to update the examples.
If there are many examples of a complicated template, later ones may break due to limits in MediaWiki; see the HTML comment "NewPP limit report" in the rendered page.

Rank 2 Dynkin diagrams
Group name	Dynkin diagram		Cartan matrix		Symmetry order	Related simply-laced automorphic group³
Group name	(Standard) multi-edged graph¹	Valued graph²	$\left[{\begin{matrix}2&a_{12}\\a_{21}&2\end{matrix}}\right]$	Determinant (4-a₂₁*a₁₂)	Symmetry order	Related simply-laced automorphic group³
Finite (Determinant>0)
A₁xA₁			$\left[{\begin{smallmatrix}2&0\\0&2\end{smallmatrix}}\right]$	4	2
A₂			$\left[{\begin{smallmatrix}2&-1\\-1&2\end{smallmatrix}}\right]$	3	3
B₂			$\left[{\begin{smallmatrix}2&-2\\-1&2\end{smallmatrix}}\right]$	2	4	${A}_{3}$
C₂			$\left[{\begin{smallmatrix}2&-1\\-2&2\end{smallmatrix}}\right]$	2	4	${A}_{3}$
G₂			$\left[{\begin{smallmatrix}2&-1\\-3&2\end{smallmatrix}}\right]$	1	6	${D}_{4}$
Affine (Determinant=0)
A₁⁽¹⁾			$\left[{\begin{smallmatrix}2&-2\\-2&2\end{smallmatrix}}\right]$	0	∞	${\tilde {A}}_{3}$
A₂⁽²⁾			$\left[{\begin{smallmatrix}2&-1\\-4&2\end{smallmatrix}}\right]$	0	∞	${\tilde {D}}_{4}$
Hyperbolic (Determinant<0)
			$\left[{\begin{smallmatrix}2&-1\\-5&2\end{smallmatrix}}\right]$	-1	∞	H₅⁽⁶⁾
			$\left[{\begin{smallmatrix}2&-b\\-a&2\end{smallmatrix}}\right]$	4-ab	∞
Note¹: The multi-edged diagram corresponds to the nondiagonal Cartan matrix elements a₂₁, a₁₂, with the number of edges drawn equal to max(a₂₁, a₁₂), and an arrow pointing towards nonunity element(s). Note²: For hyperbolic groups, (a₁₂*a₂₁>4), the multiedge style is abandoned in favor of an explicit labeling (a₂₁, a₁₂) on the edge. These are usually not applied to finite and affine graphs. Note³: Many multi-edged groups are automorphic via a folding operation with a higher ranked simply-laced group.
