COMMENTS
The morphism 0->10, 1-> 0111 has two limiting words. If the number of iterations is even, the 0-word evolves from 0 -> 10 -> 011110 -> 10011101110111011110 ->
01111010011101110111100111011101111001110111011110011101110111011110; if the number of iterations is odd, the 1-word evolves from 0 -> 10 -> 011110 -> 10011101110111011110, as in A285277.
