DihedralGroup

DihedralGroup[n]
represents the dihedral group of order .

DetailsDetails

  • The degree n of DihedralGroup[n] must be a positive integer.
  • DihedralGroup[1] is isomorphic to CyclicGroup[2] and represented by default as a permutation group on the points .
  • DihedralGroup[2] is isomorphic to AbelianGroup[{2,2}] and represented by default as a permutation group on the points .
  • For n3, DihedralGroup[n] is represented by default as a permutation group on the points .
