Around a circle i place 64 equally spaced points, so that there are 64x63 divided by2=2016 possible chords between these points. I draw some of these chords, but each chord cannot cut across more than one other chord. What is the maximum number of chords I can draw?

Could someone please give me a head start on how i should approach this problem. Its been bugging me for weeks, thanks.

  1. try nesting polygons
    ... going from the outside in

    connecting adjacent points gives 64 sides (chords)

    every other point gives 32 sides

    every 3rd point. etc...
