A theorem of Lackenby and Meyerhoff, whose proof relies on the geometrization conjecture and computer assistance, holds that 10 is the largest possible number of exceptional surgeries of any hyperbolic knot. However, it is not currently known whether the figure-eight knot is the only one that achieves the bound of 10.
80 is: the sum of Euler's totient function φ( x ) over the first sixteen integers. a semiperfect number , since adding up some subsets of its divisors (e.g., 1 , 4 , 5 , 10 , 20 and 40 ) gives 80.
The simplest example of a non-invertible knot is the knot 8 17 (Alexander-Briggs notation) or .2.2 (Conway notation). The pretzel knot 7, 5, 3 is non-invertible, as are all pretzel knots of the form (2 p + 1), (2 q + 1), (2 r + 1), where p , q , and r are distinct integers, which is the infinite family proven to be non-invertible by Trotter.
