%N A037314 Numbers n such that (sum of base 3 digits of n)=(sum of base 9 digits 
               of n).
%C A037314 a(n)=Sum{d(i)*9^i: i=0,1,...,m}, where Sum{d(i)*3^i: i=0,1,...,m} is 
               the base 3 representation of n.
%F A037314 Numbers that can be written using only digits 0, 1 and 2 in base 9. Also, 
               write n in base 3, read as base 9: (3) [n] (9) in base change notation. 
               a(3n+k) = 9a(n)+k for k in {0,1,2}. - Frank Adams-Watters (FrankTAW(AT)Netscape.net),
