We enumerate graph homomorphisms to quasi-complete graphs, i.e., graphs
obtained from complete graphs by removing one edge. The source graphs
are complete graphs, quasi-complete graphs, cycles, paths, wheels and
broken wheels. These enumerations give rise to sequences of integers
with two indices; one of the indices is the number of vertices of the
source graph, and the other index is the number of vertices of the
