The permutationEquation function you provided seems to implement the permutation equation method in Python. This method takes a list p as input and returns a list of values based on the permutation equation.

Let's break down the code to understand how it works:

The function permutationEquation takes a list p as an argument.

It initializes an empty list called result to store the computed values.

It iterates over the range of indices of the input list p using the range function.

Inside the loop, it calculates p1 by finding the index of i+1 in p and adding 1 to it. The index function returns the index of the first occurrence of the specified value in the list.

Then, it finds the index of p1 in the list p using the index function again, and adds 1 to it.

The computed value is then appended to the result list.

After the loop completes, the function returns the result list.

This function essentially calculates the permutation equation p(p(y)) = x for each value x in the input list p and returns the resulting list.

Please note that the code assumes that the input list p is 1-based indexed (i.e., the values start from 1). If the input list is 0-based indexed, the code would need to be modified accordingly.

The

`permutationEquation`

function you provided seems to implement the permutation equation method in Python. This method takes a list`p`

as input and returns a list of values based on the permutation equation.Let's break down the code to understand how it works:

`permutationEquation`

takes a list`p`

as an argument.`result`

to store the computed values.`p`

using the`range`

function.`p1`

by finding the index of`i+1`

in`p`

and adding 1 to it. The`index`

function returns the index of the first occurrence of the specified value in the list.`p1`

in the list`p`

using the`index`

function again, and adds 1 to it.`result`

list.`result`

list.This function essentially calculates the permutation equation

`p(p(y)) = x`

for each value`x`

in the input list`p`

and returns the resulting list.Please note that the code assumes that the input list

`p`

is 1-based indexed (i.e., the values start from 1). If the input list is 0-based indexed, the code would need to be modified accordingly.
