A189628 is one of many 01-sequences fixed by morphisms. An extension of the list begun at A189576 is continued here with sequences of type 3,3.
Each row shows a morphism, followed by four sequences:
(1) the fixed sequence a [starting from a(0)=0],
(2) positions of 0 in a,
(3) positions of 1 in a,
(4) partial sums of a.
Some lower-numbered entries are conjectural.
