%N A131102 Prime numbers arising from A131101.
%C A131102 The Safe Primes (A005385) they are part of this sequence because they 
               are the result of add A005384(n) (Sophie Germain primes) to its only 
               prime factor (itself) + 1 = 2*A005384 + 1 .
%F A131102 A131101(n) + prime factors of A131101(n) + 1 = a(n) ; a(n) is a prime 
               number.
%e A131102 a(8)=59 because 59 = A131101(8)+ prime factors of A131101(8) +1 = 29+ 
               (29) +1 ; a(9)=41 becasue A131101(9)+ prime factors of A131101(8) 
               + 1 = 30 +(2+3+5)+1.
