%N A246821 Max _{2<=k<=n} floor(A242720(k)/prime(k)) - prime(n).
%C A246821 Conjecture: a(n) = o(prime(n)), as n goes to infinity.
%C A246821 If the conjecture is true, then A242720(n) ~ prime(n)^2. Indeed, A242720(n) >= prime(n)^2 + 2*prime(n) + 3; on the other hand, by the conjecture, we have A242720(n)/prime(n) <= a(n) + 1 + prime(n) = prime(n)*(1+o(1)).
