SymPy | Permutation.rmul() in Python

Last Updated : 27 Aug, 2019

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)
