Query: The general position problem on Kneser graphs and on some graph
  operations   A vertex subset $S$ of a graph $G$ is a general position set of $G$ if no
vertex of $S$ lies on a geodesic between two other vertices of $S$. The
cardinality of a largest general position set of $G$ is the general position
number (gp-number) ${\rm gp}(G)$ of $G$. The gp-number is determined for some
families of Kneser graphs, in particular for $K(n,2)$ and $K(n,3)$. A sharp
lower bound on the gp-number is proved for Cartesian products of graphs. The
gp-number is also determined for joins of graphs, coronas over graphs, and line
graphs of complete graphs.
