A schematic representation of four party voting compositions.

An equilateral tetrahedron is unfolded to illustrate one possible way of showing the voting composition in Scotland.

The diagram shows how a tetrahedron can be drawn as a net of four equilateral triangles, each possibly containing the group of places which would be closest to that side, if the places were projected in a three dimensional analogue of the electoral triangle. The net can be subdivided into twenty-four areas, each containing a particular ordering of the parties. The order for any one party forms a star like shape, centred on its apex shown here for the Conservatives. Each triangle of the net contains all those places where one particular party came in fourth position.
