资源简介:
This dataset contains low stick number representatives for all knot types. For knot types where the stick number was known at the time of deposit, these polygons match the minimal stick number. The file stick-number-bounds.nc is a NetCDF file containing stick data on all knots through 13 crossings. Each knot type has 4 pieces of data associated to it: number of sticks, number of crossings, vertex coordinates, and PD code of the minimal stick representative. So for the knot 10_37 these are located at 10_37/sticks, 10_37/crossings, 10_37/coords, and 10_37/pdcode. Note that PD codes are 0-indexed and knot names follow the Rolfsen convention through 10 crossings (8_18, 9_29, etc.) and the Dowker–Thistlethwaite convention for knots with 11–13 crossings (K11a367, K12n242, etc.). For knots through 12 crossings, the vertex coordinates are also given in a separate tab-separated file. Just search for the knot name below.
