Abstract: Paul Erdos asked the following question in the 60's: How many collinear k-tuples can a planar n-point set contain, if it contains no k+1 points on a line? (k>3, fixed) We will present an elementary construction that significantly improves the previously known lower bound for this value.
Joint work with József Solymosi.
