WebBurnside's lemma, sometimes also called Burnside's counting theorem, the Cauchy-Frobenius lemma or the orbit-counting theorem, is a result in group theory which is often useful in taking account of symmetry when counting mathematical objects.Its various eponyms include William Burnside, George Pólya, Augustin Louis Cauchy, and Ferdinand … WebThe Orbit Counting Lemma is often attributed to William Burnside (1852–1927). His famous 1897 book Theory of Groups of Finite Order perhaps marks its first ‘textbook’ appearance but the formul a dates back to Cauchy in 1845. ...

Orbit-Stabilizer Theorem - ProofWiki
WebThe Orbit-Stabiliser Theorem is not suitable for this task; it relates to the size of orbits. You're instead after the number of orbits, so it's better to use the Orbit-Counting Theorem (=Burnside's Lemma), or its generalisation Pólya Enumeration Theorem (as in Jack Schmidt's answer). – Douglas S.
