SymPy | Permutation.rmul() in Python
Permutation.rmul() : rmul() is a sympy Python library function that returns the product of the permutation.
Syntax : sympy.combinatorics.permutations.Permutation.rmul()
Return : product of the permutation.
Code #1 : rmul() Example
# Python code explaining # SymPy.Permutation.rmul()   # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation   # Using from sympy.combinatorics.permutations.Permutation.rmul() method   # creating Permutation a = Permutation([[2, 0], [3, 1]])   b = Permutation([1, 3, 5, 4, 2, 0])     print ("Permutation a - rmul form : ", a.rmul(b)) print ("Permutation b - rmul form : ", b.rmul(a)) |
Output :
Permutation a – rmul form : (0 1 3 4 2 5)
Permutation b – rmul form : (0 2)(1 3)
Code #2 : rmul() Example – 2D Permutation
# Python code explaining # SymPy.Permutation.rmul()   # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation   # Using from # sympy.combinatorics.permutations.Permutation.rmul() method   # creating Permutation a = Permutation([[2, 4, 0],                  [3, 1, 2],                  [1, 5, 6]])     print ("Permutation a - rmul form : ", a.rmul(a)) |
Output :
Permutation a – rmul form : (0 3 5 6 1 2 4)
