https://oeis.org/A165221 (The Padovan sequence analog of the Fibonacci 
"rabbit" constant binary expansion....) claims in its name to be the 
concatenation of certain finite sequence, the first several of which 
are listed there. However, it isn't. Can anyone figure out what this is 
supposed to be?

Improved references would be good, too. Are these books? articles? In 
either case, published by whom, when, and where?
