COMMENTS
| For n>=1 sequence {a(n+1)} is the minimal recursive such that A007814(a(n+1))=A007814(n). [From Vladimir Shevelev (shevelev(AT)bgu.ac.il), Apr 27 2009]
A053645(a(n)) = n-1 for n>0 . [From Reinhard Zumkeller (reinhard.zumkeller(AT)gmail.com), May 20 2009]

FORMULA
| For n>0, a(n) = 3n - 2 - A006257(n-1). - Ralf Stephan (ralf(AT)ark.in-berlin.de), Sep 16 2003
a(0) = 0, a(1) = 1, for n>0: a(2n) = 2*a(n) + 1, a(2n+1) = 2*a(n+1) . - DELEHAM Philippe (kolotoko(AT)wanadoo.fr), Feb 29 2004
For n>=2, A007814(a(n))=A007814(n-1). [From Vladimir Shevelev (shevelev(AT)bgu.ac.il), Apr 15 2009]
a(n+2)=min{m>a(n+1): A007814(m)=A007814(n+2)}; A010060(a(n+1))= 1-A010060(n). [From Vladimir Shevelev (shevelev(AT)bgu.ac.il), Apr 27 2009]
