No other terms below 10^14.
If prime p does not divide any of the first A227944(p) <= log_2(p) terms of A318970, then p does not divide any term of A318970, i.e., p does not belong to this sequence.
(2^260+5)/261 is a term (76-digit prime). Hence, a(5) <= (2^260+5)/261.
Any prime p with A318989(p)=0 belongs to this sequence. However, it is unknown if there is a term p with nonzero A318989(p).
