We present a new sieve for the distinct coordinate counting problem. This significantly improves the classical inclusion-exclusion sieve for this problem, in the sense that the number of terms is reduced from 2(k2) to k!, and reduced further to p(k) in the symmetric case, where p(k) denotes the number of partitions of k. As an illustration of applications, we give an in-depth study of a basic example arising from coding theory and graph theory.
