Like A006920 but starting from a(0)=0.

			a(2) = 1|1 because there is 1 zero and 1 one in the entries a(0) and a(1).
a(3) = 1|3 because there are 1 zero and 3 ones in the entries a(0) to a(2).
a(7) = 4|12|1|2|1|0|1|0|1 because there are 4 zeros, 12 ones, 1 two, 2 threes, 1 four, 0 fives,..., 1 eight in the entries a(0) to a(6).
