%N A368497 Decimal expansion of the fixed point c = S(c) of S(x) = Sum_{k>=1} (prime(k) - x) / Product_{i=1..k-1} prime(i).
%C A368497 S(x) = (1-x)*(1+A064648) + A249270 is linear so the fixed point is unique.
%C A368497 With this constant as h(1) = c, sequence h(n+1) = ceiling(h(n)) * (h(n) - ceiling(h(n)) + c) is real numbers with the property that ceiling(h(n)) = prime(n).
%F A368497 Equals (A249270 + A064648 + 1)/(A064648 + 2).
