Burnsides lemma

Lemma 14.18. 2013-07-08 Counting concerns a large part of combinational analysis. Burnside's lemma, sometimes also called Burnside's counting theorem, the Cauchy-Frobenius lemma or the orbit-counting theorem, is often useful in taking account of symmetry when counting mathematical ob-jects. Section 15.3 Burnside's Lemma.

Burnsides lemma

Or you can count the number of necklaces, without reflections. 2013-07-08 · Burnside’s Lemma now gives For example there are ways of colouring the faces of a cube in Red and Black. Burnside’s Lemma can help us understand in how many ways we can freely colour the faces of a cube, or the beads of a necklace. Burnside's lemma helpfully validates the computations we did in the previous section. However, what if instead of a square we were working with a hexagon and instead of two colors we allowed four? Then there would be \(4^6=4096\) different colorings and the dihedral group of the hexagon has \(12\) elements.

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.

Since the group of permutations in a typical problem is fairly small, the sum in Burnside's Theorem is usually manageable.
