COMMENT
|
Vardi gives several identities satisfied by A001463 and this sequence.
The g.f. (-1+z**4+z**7-z**8+z**9-z**3-z-z**11+z**12)/(1+z)/(z**2+1)/(z-1)**3 conjectured by S. Plouffe in his 1992 dissertation is wrong.

FORMULA
|
a(n) is asymptotic to tau^(1-tau)*n^tau where tau is the golden ratio, tau=(1+sqrt(5))/2. More precisely, a(n)= tau^(1-tau)*n^tau + c*n^(1/tau)+0(n^(1/tau)) where c is a constant around 0.6. Is there any known value for c? - Benoit Cloitre (benoit7848c(AT)orange.fr), Oct 29 2002
