COMMENTS
The morphism 0->11, 1-> 011 has two limiting words. If the number of iterations is even, the 0-word evolves from 0 -> 11 -> 011011 -> 1101101111011011 -> 01101111011011110110110110111101101111011011; if the number of iterations is odd, the 1-word evolves from 0 -> 11 -> 011011 -> 1101101111011011, as in A285421.
