Distance between two knots
You might be interested in the work by Stasiak (the famous 1/7 writhe guy :-) who made a paper on the, well, I call it "genealogy" of knots. Should be something like Stasiak&Flammini, "Natural classifications of knots". (Oh, and I extended that work long before that paper came out :-) |

A property of Mersenne primes
You say "unusually". Is this the only f which has the properties needed for the proof or do we have some leeway, like A*y^2+B instead of y^2? |

Highest weight formulas for quadratic Casimir and dimension for the simply laced Lie algebras
In fact, this question can be closed: a) I found a Chinese (:-) site which wonderfully explained how to apply the Weyl formula step by step, and I immediately understood everything. It IS simple but I never would have understood your standard abstract textbook. And b), the formula for the quantum dimension will be automatically correct for the Casimir by the replacements I described, but not in reverse - you can do nice fully general Casimir formulas for laced Dynkin diagrams OR Bn+Cn+F4, but unfortunately, this doesn't hold for the quantum dimensions and my work was a bit pointless. |

Argl. Example wasn't formulated precisely enough. |

Noncommutative fusion categories
Doesn't matter insofar as I just fell over Haagerup 2 (also called H6) in arxiv1102.2631v2 which I forgot - so we're down to rank 6 anyway. |

Fusion categories: If infinity were an integer
So, loosely, a based ring is a category iff it has a consistent (pentagon rule etc.) set of 6j symbols? |
