 OFFSET 1,2 COMMENTS Method of creation of sequence a(n) from b(n) = A018252(n): Take b(1) and put in vacancy place a(1), swap this place and b(1), repeat with b(2), b(3), ...: b(1) = 1, a(1) = 1, b(2) = 4, a(2) = 4, a(4) = 2, b(3) = 6, a(3) = 6, a(6) = 3, b(4) = 8, a(5) = 8, a(8) = 5, b(5) = 9, a(7) = 9, a(9) = 7, ... LINKS FORMULA a(n) = A135761(n) for n >= 11. a(n) = A181097(n) for n >= 11.
