Aug 5, 2010 at 22:06 comment added Peter Samuelson This is very interesting! It looks like they were trying to answer almost the exact same question that I asked, and in addition to adding operations, they also expanded "all knots" to "all knotted trivalent graphs." (If I had thought of this possibility (expanding "knots" to "knots + other things") I would have written the question differently to include that possibility also.)
