 A065670 Permutation of N induced by rotating the node 6 right in the infinite planar binary tree shown at A065658. 2
 1, 2, 115, 4, 5, 234881023, 7, 8, 9, 10, 11, 877, 112, 475, 15, 16, 17, 18, 19, 20, 21, 22, 23, 52, 445, 57355, 3616, 235, 1915, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 103, 13, 14191, 28615, 917506, 229630, 3613, 454, 934, 120832 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 LINKS EXAMPLE This permutation touches only the rationals in the range ]1/2, 3/4[, which for example contains the sixth node = 3/5 of the SB ]0,1[ tree (A007305/A007306) which has an infinite, but periodic binary fractional expansion 0.100110011001... and by this permutation it is changed to 0.1010100110011001... = 53/80, which is located as the 234881023th node in the SB ]0,1[ tree. MAPLE [seq(RotateBinFracNodeRight(6, j), j=1..256)]; CROSSREFS The sixth row of A065658. Inverse of A065671. Sequence in context: A157068 A008271 A209184 * A105327 A260334 A257939 Adjacent sequences:  A065667 A065668 A065669 * A065671 A065672 A065673 KEYWORD nonn AUTHOR Antti Karttunen, Nov 22 2001 STATUS approved
