%t A030190 Flatten[ Table[ IntegerDigits[n, 2], {n, 0, 26}]] (from Robert G. Wilson 
               v Mar 08 2005)
%Y A030190 Cf. A007376, A003137. Same as and more fundamental than A030302, but 
               I have left A030302 in the table because there are several sequences 
               that are based on it (A030303 etc.). - N. J. A. Sloane (njas(AT)research.att.com).
%Y A030190 a(n) = T(A030530(n), A083652(A030530(n))-n-1), T as defined in A083651, 
               a(A083652(k))=1.
