 A261725 Lexicographically earliest sequence of distinct terms such that the absolute difference of two successive terms is a power of 10, and can be computed without carry. 2

 OFFSET 0,3 COMMENTS In base 10, two successive terms have the same representation, except for one position, where the digits differ from exactly one unit. This difference can occur on a leading zero. Conjectured to be a permutation of the nonnegative integers. See A261729 for putative inverse. a(n) = A003100(n) for n < 101, but a(101) = 180, A003100(101) = 191. a(n) = A118757(n) for n < 201, but a(201) = 281, A118757(201) = 290. a(n) = A118758(n) for n < 100, but a(100) = 190, A118758(100) = 109. a(n) = A174025(n) for n < 100, but a(100) = 190, A174025(100) = 199. a(n) = A261729(n) for n < 100, but a(100) = 190, A261729(100) = 109.
