Has anyone tabulated the number of positions are reachable (from the
initial cube) in one move, two moves, etc.? Is the diameter of the
graph known?

In the quarter turn metric, the number of positions has been tabulated
out to eleven moves from Start. The diameter of the graph is known to be
at least 24 quarter turns because there is one position whose length has
been verified to be 24q.
