I am after someone who has some expertise in the branch of mathematics known as knot theory. Basically I have two similar knots and I can't make up my mind if they do or don't 'fall out' if one undresses the knots. (Think of a simple loop and a overhand knot; the loop will fall out whilst the overhand knot will remain if you shake the rope.) Is there a caver who has some experience of this specialist field, or even knows someone who does who would be prepared to help?
