%N A104536 Let q(b-1)=k(b)*q(b)^p(b)-1 for b=n to 1, where q(n)=p(n+1), with p(x) 
               as the x-th prime. If k(b) is the minimum positive integer that makes 
               q(b-1) prime, then a(n)=q(0).
%C A104536 a(5) has 2884 digits.
%e A104536 if n=3, then p(n+1)=p(4)=7.
%e A104536 when b=3, q(b)=q(3)=p(4)=7 and k(b)=2 and p(b)=p(3)=5, then q(b-1)=q(2)=2*7^5-1=33613
%e A104536 when b=2, q(b)=q(2)=33613 and k(b)=26 and p(b)=p(2)=3, then q(b-1)=q(1)=26*33613^3-1=987404664412321
%e A104536 when b=1, q(b)=q(1)=987404664412321 and k(b)=98 and p(b)=p(1)=2, then 
               q(b-1)=q(0)=98*987404664412321^3-1=95546861187714408803829067490017
