Each term of sequence A175335 exists in this sequence.
EXAMPLE
10 (decimal), a term of the sequence, written in binary is 1010. Letting j={0}, we have that the decimal value of 1010 U 0 U 1010 U 0 = 1010010100, which is 660, is in the sequence.
Letting j = the empty string instead, and keeping a(k) = 10, we have the concatenation 1010 U 1010, which is 10101010. This is 170 in decimal, so 170 is in this sequence.
