 OFFSET 1,2 COMMENTS A={a(n)} is self-similar in the sense that the subsequence remaining after deleting the first occurrence of each integer is identical to the original sequence A (Kimberling's "upper-trimming" operation). Fixed points of the transform are listed in A048328. Paolo P. Lava, Mar 02 2015 LINKS Indranil Ghosh, Table of n, a(n) for n = 1..59049 EXAMPLE a(33)=19 since 33 = 1020(base 3) -> 0201(base 3) = 19.
