SymPy | Polyhedron.pgroup() in Python
Polyhedron.pgroup() : pgroup() is a sympy Python library function that returns the permutations of the polyhedra.
Syntax : sympy.combinatorics.Polyhedrons.Polyhedron.pgroup()
Return : permutations of the Polyhedron.
Code #1 : pgroup() Example – tetrahedron
# Python code explaining # SymPy.Polyhedron.pgroup() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.polyhedron import tetrahedron, octahedron # Using from # sympy.combinatorics.polyhedron.Polyhedron.pgroup() # Creating Polyhedron a = tetrahedron.copy() print ("Polyhedron - pgroup form : ", a.pgroup) a.rotate(0) print ("\nPolyhedron - pgroup form : ", a.pgroup) |
Output :
Polyhedron – pgroup form : PermutationGroup([
(1 2 3),
(3)(0 1 2),
