We prove that any thrackle of n vertices has at most 1.3984n edges. Quasi-thrackles are defined similarly, except that every pair of edges that do not share a vertex are allowed to cross an odd number of times. It is also shown that the maximum number of edges of a quasi-thrackle on n vertices is 3/2(n-1), and that this bound is best possible for infinitely many values of n.","lang":"eng"}],"volume":10692,"department":[{"_id":"UlWa"}],"title":"Thrackles: An improved upper bound","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["1708.08037"]},"day":"21","citation":{"short":"R.
