 A227741 Simple self-inverse permutation of natural numbers: List each block of A005811(n) numbers from A173318(n-1)+1 to A173318(n) in reverse order. 7
 1, 3, 2, 4, 6, 5, 9, 8, 7, 11, 10, 12, 14, 13, 17, 16, 15, 21, 20, 19, 18, 24, 23, 22, 26, 25, 29, 28, 27, 31, 30, 32, 34, 33, 37, 36, 35, 41, 40, 39, 38, 44, 43, 42, 48, 47, 46, 45, 53, 52, 51, 50, 49, 57, 56, 55, 54, 60, 59, 58, 62, 61, 65, 64, 63, 69, 68, 67, 66 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS This permutation maps between such irregular tables as A101211 and A227736 which are otherwise identical, except for the order in which the lengths of runs have been listed. In other words, A227736(n) = A101211(a(n)) and vice versa, A101211(n) = A227736(a(n)). LINKS Antti Karttunen, Table of n, a(n) for n = 1..1001 FORMULA a(n) = A173318(A227737(n)) - A227740(n). PROG (Scheme) (define (A227741 n) (- (A173318 (A227737 n)) (A227740 n))) CROSSREFS Cf. A227742 (gives the fixed points). Cf. also A227737, A227740, A005811, A173318.
