[ixhlvtqy] Multiplayer go 囲碁 with more connectivity

Modify go 囲碁 to have more than 2 players.  Each player has a different color.  We probably want nodes with more connectivity, more edges, to avoid groups from being too easily killed.  6 way connectivity with equilateral triangular lattice graph.  8 ways on a square lattice graph, but also connecting diagonals.  Higher dimensions.

Then the multiplayer game could be reduced back down to 2 players.
