[seqfan] Re: Pseudo-arithmetic progressions

[Vladimir Shevelev]

Some very plausible conjectures for A179383:

 1) The sequence consists of primes and squares of primes;
 2) The set of squares is finite;
 3) A prime p>=5 is in the sequence iff it has primitive root 2 (A001122); 
 4) For n>=2, a(n)=A139099(n+1).

Vladimir
