Query: Examples of $K3$ surfaces with real multiplication   We construct explicit examples of $K3$ surfaces over ${\mathbb Q}$ having
real multiplication. Our examples are of geometric Picard rank 16. The standard
method for the computation of the Picard rank provably fails for the surfaces
constructed.
