Final answer:
The permutation 124357869 in array form is displayed with two rows; the top row numbers 1 to 9 represent the original positions, and the bottom row represents the elements in the new permutated order, showing the changes in positions.
Step-by-step explanation:
Writing the permutation 124357869 in array form involves arranging this sequence into two rows, where the top row represents the original positions and the bottom row represents the elements in their permutated order. Here's the array form:
1 2 3 4 5 6 7 8 9
1 2 4 3 5 7 8 6 9
We see that positions 1 and 2 remain the same, swapping takes place between positions 3 and 4, 6 and 8, and all other positions are also unchanged as per the given permutation.
