a(n)=n-9*A002266(A004526(n))=n-9*A004526(A002266(n)). - Hieronymus Fischer (Hieronymus.Fischer(AT)gmx.de), Jun 17 2007
a(n)=(n+9*A010879(n))/10. - Hieronymus Fischer (Hieronymus.Fischer(AT)gmx.de), Jun 17 2007
a(n)=(n+9*A000035(n)+18*A010874(A004526(n)))/10. - Hieronymus Fischer (Hieronymus.Fischer(AT)gmx.de), Jun 17 2007
a(n)=(n+9*A010874(n)+45*A000035(A002266(n)))/10. - Hieronymus Fischer (Hieronymus.Fischer(AT)gmx.de), Jun 17 2007
