Permutation.mul_inv() : mul_inv() is a sympy Python library function that returns the mul inverse other*~self, self and other have _array_form.
Syntax : sympy.combinatorics.permutations.Permutation.mul_inv()
Return : the mul inverse other*~self, self and other have _array_form.
Code #1 : mul_inv() Example
# Python code explaining # SymPy.Permutation.mul_inv() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from # sympy.combinatorics.permutations.Permutation.mul_inv() method # creating Permutation a = Permutation([[2, 0], [3, 1]]) b = Permutation([1, 3, 5, 4, 2, 0]) print ("Permutation a - mul_inv form : ", a.mul_inv(a)) print ("Permutation b - mul_inv form : ", b.mul_inv(b)) |
Output :
Permutation a – mul_inv form : (3)
Permutation b – mul_inv form : (5)
Code #2 : mul_inv() Example – 2D Permutation
# Python code explaining # SymPy.Permutation.mul_inv() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.mul_inv() method # creating Permutation a = Permutation([[2, 4, 0], [3, 1, 2], [1, 5, 6]]) print ("Permutation a - mul_inv form : ", a.mul_inv(a)) |
Output :
Permutation a – mul_inv form : (6)
