The difference A000048 - A002823 is looks like being positive and zero at 
prime index.
But Stein's article is too complex for me.

Subject: [seqfan] 40-year old classic seq needs more terms

Dear Seq Fans, In the paper

N. Metropolis, M. L. Stein and P. R. Stein, On finite limit sets for
transformations on the unit interval, J. Combin. Theory, A 15 (1973),
25-44. Reprinted in P. Cvitanovic, ed., Universality in Chaos, Hilger,
Bristol, 1986, pp. 187-206.

there are two sequences that are emphasized, A000048 and A002823. A000048
is well understood and even has a b-file. But A002823 still only has the
first 12 terms that it did back in 1971 when Paul Stein told me about it.
Can anyone extend it?

Best regards
Neil
