Low stick number polygons for a family of pretzel knots

This dataset contains low stick number representatives for the pretzel knots where file \"stick_special_pretzel_n.tsv\" contains vertex coordinates for a polygon with pretzel knot type (2,3,...,3) with n 3's. These knots are known to have bridge index n+1 and so their stick number is at least 2n+4. The crossing number of each knot is 3n+2; for n>=3, the examples below have either 3n+2 or 3n+1 sticks.

本数据集包含普雷泽尔纽结（pretzel knots）的低杆数代表性纽结，其中文件"stick_special_pretzel_n.tsv"存储了含n个3的(2,3,…,3)型普雷泽尔纽结对应的多边形顶点坐标。已知此类纽结的桥指数为n+1，因此其杆数至少为2n+4。每个纽结的交叉数为3n+2；当n≥3时，下述示例的杆数为3n+2或3n+1。
