COMMENTS

We define the 0Ramanujan primes to be the usual primes (A000040), and we define the 1Ramanujan primes to be the Ramanujan primes (A104272).
The sequence is only conjectural without a proof of an upper bound on a(n) (like the bound A104272(n) < prime(3*n) proved by Laishram and used in computing Ramanujan primes).  Jonathan Sondow, Aug 27 2011
