(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A175480 a(1)=1. For n >= 1, if a(n) = 1, then append to the sequence the digits of binary n+1 (most significant digits first and least significant digits last). If a(n) = 0, then append to the sequence the digits of binary n+1 in reverse order (least significant digits first and most significant digits last). 2
