Hi Ken,
In a previous life over 40 years ago, I was really interested in knots and
once knew over 3000 different knots (didn't go to school much!).
I can think of several knot topologies ( a dozen?) that fit Jerry's
instructions yet are not the conventional shoelace bow - nor actually stop
the shoelaces from coming undone!
Incidentally, in 'knot language' the conventional shoelace bow could be
described something like: a sequence of two overhand knots (usually opposed
in direction) using two parts (ends) of the same cord with the main bight
acting as the standing part. The second overhand knot is tied with the
bights of both cord ends.
Best wishes,
Terry
