DESCRIPTION:Braids and Combinatorics -\nCombinatorics is\, in principle\, t
 he subject devoted to counting certain kinds of mathematical objects.  Seve
 ral objects appear regularly in this story: subsets\, partitions\, permutat
 ions\, and the like.  I’ll begin with an introduction to these objects and 
 how combinatorialists count them.  With that in hand\, I’ll discuss “braide
 d” analogues of these constructions — these have a much more geometric flav
 or\, but still retain some of the original combinatorial aspects.  This all
 ows us to upgrade the familiar notions of finite sets and functions between
  them to a world of braided sets and functions.
