Query: Complete Graphs and Polyominoes   In the chip-firing variant, Diffusion, chips flow from places of high
concentration to places of low concentration (or equivalently, from the rich to
the poor). We explore this model on complete graphs, determining the number of
different ways that chips can be distributed on an unlabelled complete graph
and demonstrate connections to polyominoes.
