Orbit-Stabilizer Theorem/Examples - ProofWiki

Weborbit - stabilizer theorem ( uncountable ) ( algebra) A theorem which states that for each element of a given set that a given group acts on, there is a natural bijection between the orbit of that element and the cosets of the stabilizer subgroup with respect to that element. Categories: en:Algebra WebHence the stabilizer of a vertex under rotations of the cube consists of three elements: 1. the identity rotation (by 0 or 2 π or − 24 π, it's all the same symmetry), 2. rotation about the long diagonal axis by 2 π / 3 and 3. by twice that.

Specifically, let be a monoid operating on a set , and let be a subset of . The stabilizer of , sometimes denoted , is the set of elements of of for which ; the strict stabilizer' is the set of for which . In other words, the stabilizer of is the transporter of to itself. http://sporadic.stanford.edu/Math122/lecture14.pdf port hadlock sheriff office
