Playing With Pyramids says in multiple places that a koan has one or more pyramids. The null koan is an obvious variant that lots of people allow, but I prefer to disallow it because of the ambiguity of rules like "contains only grounded pyramids".
The usual reason I see for disallowing it is that a marked null koan looks like "Someone dropped a marking stone on that unused section of table".
Still, it's good for the Master to think about it when creating a rule, to make sure there isn't any ambiguity with things like "all" or "any".
