Burnside's Lemma is also called the Pólya-Burnside Lemma, the Cauchy- Frobenius Lemma, or even "the lemma that is not Burnside's". It can be used for counting

It is one of the results of group theory. It is used to count distinct objects Burnside's lemma helps us solve the following problem: Example 1. Find the number of distinct cubes that can be made by painting each face of a given cube in Burnside's lemma, sometimes also called Burnside's counting theorem, the Cauchy–Frobenius lemma, orbit-counting theorem, or The Lemma that is not article introduces Burnside's lemma which is a powerful method for handling such problems. It requires a knowledge of group theory, but is not so difficult.

Perhaps you can look at this same question with any number of beads (say 6). Or you can count the number of necklaces, without reflections.

Define. FixΩ(g) = {α ∈ Ω: g(α) = α}, F i x Ω ( g) = { α ∈ Ω: g ( α) = α }, that is, the set of all colourings fixed by a given symmetry. Burnside’s lemma provides a way to calculate the number of equivalence classes.
If Gis a group, then jGjrepresents the number of elements in Gand is called the order of the group. Finally, if we have a group of permutations of a set S, then jGjis the degree of the permutation group. Burnside's Counting Theorem offers a method of computing the number of distinguishable ways in which something can be done. In addition to its geometric applications, the theorem has interesting applications to areas in switching theory and chemistry.

An Application of Burnside's Theorem to Music Theory. Jeff Graham using Burnside's Lemma (Neumann [1979] recounts its history) for doing the counting.
2021-01-25 · Burnside’s Lemma is also sometimes known as orbit counting theorem.
Burnside's Lemma. Burnside's lemma is a result in group theory that can help when counting objects with symmetry taken into account. It gives a formula to count objects, where two objects that are related by a symmetry (rotation or reflection, for example) are not to be counted as distinct.

L¨ osning: Vi listar upp gruppen G av alla vridningar som avbildar kvadraten p˚ a sig sj¨alv Burnside's lemma, sometimes also called Burnside's counting theorem, the Cauchy–Frobenius lemma, orbit-counting theorem, or The Lemma that is not Burnside's, is a result in group theory which is often useful in taking account of symmetry when counting mathematical objects. Burnside's lemma is a result in group theory that can help when counting objects with symmetry taken into account. It gives a formula to count objects, where two objects that are related by a symmetry (rotation or reflection, for example) are not to be counted as distinct. Burnside's Lemma is a combinatorial result in group theory that is useful for counting the orbits of a set on which a group acts. The lemma was apparently first stated by Cauchy in 1845. Hence it is also called the Cauchy-Frobenius Lemma, or the lemma that is not Burnside's.
