Lecture Notes in Mechanical EngineeringGiven an n × n grid of n. points we must select as many as possible so that no three are in a straight line. This paper reviews results concerning the problem and provides a few minor proofs, additions and generalisations.

Sum-free sets, difference sets and cyclotomy,e set T such that S⊑T⊑G, we have S = T..Here we determine some sum-free cyclotomic classes in finite fields and from them, we construct new supplementary difference sets, association schemes and block designs. We also continue our study of locally maximal sum-free sets in groups of small orders and in finite fields.
