COMMENTS
The sequence is conjectured to be a permutation of the positive integers. In the first 20000 terms there are twenty-five fixed points starting 3, 37, 84, 99, 103, 166.

EXAMPLE
a(5) = 12 as a(1) + a(2) + a(3) + a(4) + 12 = 1 + 2 + 3 + 5 + 12 = 23 = 10111_2, and "10111" appears in the string concatenation of the binary values of a(1)..a(4) = "11011101".
