Hexagon Problem

The puzzle - to put all seven Hexagons one in the centre, the rest around it, such that adjacent triangles of adjacent Hexagons have the same colour.

You can see one solution is found. Press ShowMoves to see how it does it - using backtracking - where the program tries to place a hexagon in a position, and if successful tries to place one in the next. If it cant find a place in the next position the current choice must be wrong, so the program looks for another hexagon for that position.

If you select Find All, then all solutions are found - then press ShowSolns to see them.
