By definition of A084937 this cannot contain two consecutive 0's. So the 0's divide this sequence into runs of 1's and 2's. In the first 100000 terms the following runs of 1's and 2's appear: 11, 12, 21, 22, 111, 112, 121, 122, 211, 212, 221, 222, 1112, 1121, 1122, 1212, 1221, 2111, 2112, 2121, 2211, 2212, 2221. There is no obvious structure. - N. J. A. Sloane, Nov 07 2014
