That A189664 0->010, 1->001 should be parity of how many ternary
1-digits below the lowest 0-digit in n-1.  Don't know any particular
significance to such a count though.  Perhaps you have this already.
All the fixed-width morphisms must have some digit interpretation, but
greater or lesser mouthful to write or want to think about :).
