WebThe Pólya–Burnside enumeration theorem is an extension of the Pólya–Burnside lemma, Burnside's lemma, the Cauchy–Frobenius lemma, or the orbit‐counting theorem. [more] … WebThe theorem is primarily of use when and are finite. Here, it is useful for counting the orbits of . This can be useful when one wishes to know the number of distinct objects of some sort up to a certain class of symmetry . For instance, the lemma can be used to count the number of non- isomorphic graphs on vertices.
