[computer-go] Big board. Torus ?

[Nick Apperson]

I considered making a version of go that plays with tetrahedral geometry.
It is a 3D arrangment where all nodes have 4 neighbors and the angles
between each are 109 degrees.  Its connection properties though are very
different because of the way it it layed out.  Hence, I am going to have to
disagree.  But if what you mean is that all that matters is the graph
representation of the go board, I will agree with you there.
