A move is to pick up a stack S and set it on another stack whose top radius exceeds the bottom radius of S; this causes the two disks that come in contact to fuse.
I'm at least as perplexed as Fred here. Where it says "In a general position there will be stacks of fused disks" does that mean each stack is entirely fused, or just that it consists of a stack of fused stacks? I don't see how the description of play can lead to anything but each stack being entirely fused, yet as Fred points out, that makes "solving" the puzzle all too obvious. (There is nothing about what constitutes a solution, so maybe that's where the confusion lies?) Perhaps Alex can clarify this? --Dan ________________________________________________________________________________________ "Outside of a dog, a book is man's best friend.
