Zak and Ray explained the problem. Zak's program implements the definition properly, so Zak should submit it (perhaps adding a comment of explanation too?), and if Zak does that perhaps he could also fix the 11-versus-19 error in the example?
Thanks for the explanation.

Sorry, too quick on the response. Yes the example is wrong because 1011 in base 2 is 11, not 19 as you said.
Of course the base 9 representation of the initial prime must contain only digits < 2. Could that be why you are seeing more terms?
