Three small triangulated categories

These are pictures of (the graphs underlying) the Auslander-Reiten quivers of three triangulated categories with finitely many indecomposables. The visualization software is javaview. You can rotate and scale the pictures (click and s+click) or open them in a separate, resizeable window (right click). The coordinates of the vertices were computed using the quiver mutation applet.
