Aim - 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 try to find one solution. Press ShowMoves to see how - 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 the current choice must be wrong so another is sought.
You can Find All, then all solutions are found - press ShowSolns to see them.
You can shuffle the colours of the hexagons.
