%N A118247 a(0)=0. Concatenate onto the end of the sequence (from left to right) 
               the integer m_n converted into binary (with the most significant 
               digit on the left), where m_n is the smallest integer > A118248(n-1) 
               and whose binary representation does not occur anywhere earlier in 
               the sequence (when the concatenated sequence is read from left to 
               right). A118248(n) then equals m_n when written in decimal.

%e A118247 The sequence begins 0,1,1,0,1,0,0,1,1,1,1,0,0,0. Now A118248(5) = 8, 
               which is represented by the 1,0,0,0 at the end of the sequence. The 
               binary representation of 9 (1001 in binary) and (decimal) 10 (1010 
               in binary) both occur earlier in the sequence. But the binary representation 
               of (decimal) 11 (1011 in binary) does not occur earlier in the sequence, 
               so (1,0,1,1) is added to the end of the sequence. And A118248(6) 
               becomes 11.
