The number of polynomials is the number of distinct graph_id values. (You probably have a separate table for graphs; in this case, the SELECT DISTINCT subqueries can be replaced with SELECT graph_id FROM graph.) To count unique polynomials, we exclude any that are duplicates. A polynomial is a duplicate if there exists any other polynomial with a smaller ...
