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 %e A104536 then a(3)=q(0)=95546861187714408803829067490017 %Y A104536 Sequence in context: A125041 A013806 A147671 this_sequence A013882 A157255 A114432 %Y A104536 Adjacent sequences: A104533 A104534 A104535 this_sequence A104537 A104538 A104539 %K A104536 nonn %O A104536 1,1 %A A104536 Ray G.
