%N A090718 Let p run through the primes; write p in base 10 and then interpret it 
               in base 128 getting a number q; if q is prime then adjoin q to the 
               sequence.
%e A090718 2 -> 2, prime, so add 2 to the sequence;
%e A090718 11 -> 129, not prime, so 129 is not added to the sequence;
%e A090718 13 -> 131, prime, so add 131 to the sequence; etc.
