DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WCS/57/">Com
 pact packings of the plane with discs</a>\nby Miek Messerschmidt (Pretoria
 ) as part of Warwick Combinatorics Seminar\n\n\nAbstract\nAfter explaining
  what a compact packing of the plane by discs is\, I will discuss the foll
 owing question: "For which $n$-tuples of distinct positive real numbers is
  there a compact packing of the plane with discs\, so that\, firstly\, onl
 y the mentioned $n$ numbers are used as radii of discs in the packing\, an
 d secondly\, every one of the mentioned $n$ numbers occurs at least once a
 s a radius of a disc in the packing?"\n\nI will discuss some aspects of th
 is question along with its history\, which is surprisingly recent (e.g.\, 
 the case $n=2$ was only solved in 2006).\n
