SymPy | Polyhedron.cyclic_form() in Python

Polyhedron.cyclic_form() : cyclic_form() is a sympy Python library function that returns the indices of the corners in cyclic notation.

Syntax :
sympy.combinatorics.Polyhedrons.Polyhedron.cyclic_form()

Return :
indices of the corners in cyclic notation

Code #1 : cyclic_form() Example – tetrahedron

# Python code explaining
# SymPy.Polyhedron.cyclic_form()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron

# Using from
# sympy.combinatorics.polyhedron.Polyhedron.cyclic_form()

# Creating Polyhedron
a = tetrahedron.copy()

print ("Polyhedron - cyclic_form form : ", a.cyclic_form)

a.rotate(0)
print ("\nPolyhedron - cyclic_form form : ", a.cyclic_form)

Output :

Polyhedron – cyclic_form form : []

Polyhedron – cyclic_form form : [[1, 2, 3]]

Code #2 : cyclic_form() Example – octahedron

# Python code explaining
# SymPy.Polyhedron.cyclic_form()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.polyhedron import tetrahedron, octahedron

# Using from
# sympy.combinatorics.polyhedron.Polyhedron.cyclic_form()

# Creating Polyhedron
a = octahedron.copy()

print ("Polyhedron - cyclic_form form : ", a.cyclic_form)

a.rotate(0)
print ("\nPolyhedron - cyclic_form form : ", a.cyclic_form)

Output :

Polyhedron – cyclic_form form : []

Polyhedron – cyclic_form form : [[1, 2, 3, 4]]
