I and Allan Lee are engaged isotopic transformation node 6.3 (bowline #1010 closed on the front (regular) side). This can be seen as a game. The first level of this game looks like.

In the fourth level, we come from a long representation of a node to its closed tabular version and build of different symmetric diagrams, and seven intersections.
