On caps and cap partitions of Galois projective spaces
A collection \(K\) of points in \(PG(N,q)\) is called a cap if no three points of \(K\) are collinear. The authors study group actions whose orbits, or sometimes even unions of orbits, are caps. In this way, they also get partitions of \(PG(N,q)\) into caps.
