COMMENTS
The morphism 0->11, 1-> 001 has two limiting words. If the number of iterations is even, the 0-word evolves from 0 -> 11 -> 001001 -> 11110011111001 ->
00100100100111110010010010010011111001; if the number of iterations is odd, the 1-word evolves from 0 -> 11 -> 001001 -> 11110011111001 , as in A285403.
