%C 2.54 = 127/50 [From _Eric Desbiaux_, Nov 16 2008]
%F f(n) = n/2.54.
%F _Eric Desbiaux_ suggested (Apr 19 2008) that A047332(n)-A080686(n) =? a(n-1), but R. J. Mathar points out that this is only true for the first 23 terms and so is nothing more than a coincidence. - _N. J. A. Sloane_, Apr 26 2008
