Progress in the no-three-in-line problem. II
[For Part I and a description of the problem, see J. Comb. Theory, Ser. A 60, No. 2, 305-311 (1992; Zbl 0774.05025).] In Part II the author presents first solutions for \(n=33, 37, 39, 41, 43, 45, 48, 50\), and 52. Pictorial versions of some new configurations are given. For \(n=26\) a sixth configuration having reflection symmetry in a mid-perpendicular was found.
