A self-inverse permutation of the positive integers with no fixed points; A073675 composed with A120229.
The permutation swaps pairs of integers whose ratio is 1:6 or 2:3, these ratios corresponding to the factorizations 1*6 = 2*3 = 6. Row 6 is the first row of A059897 to exhibit more than 1 such ratio.
(End)
The integers in the pairs with ratio 1:6 are listed in A036668, the integers in the pairs with ratio 2:3 are listed in A325424. - Peter Munn, Mar 05 2020
