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.
