%N 0-limiting word of the morphism 0 -> 1, 1 -> 0110.
%C The morphism 0 -> 1, 1 -> 0110 has two limiting words. If the number of iterations is even, the 0-word evolves from 0 -> 1 -> 0110 -> 1011001101 -> 0110101100110110110011010110; if the number of iterations is odd, the 1-word evolves from 0 -> 1 -> 0110 -> 1011001101, as in A284656.
