%N A068172 Define an increasing sequence as follows. Given the first term called 
               the seed (the seed need not have the property of the sequence.). 
               Subsequent terms are defined as obtained by inserting/placing digits 
               (at least one) in the previous term to obtain the smallest number 
               with a given property. This is the growing prime sequence for the 
               seed a(1) = 7.
%e A068172 The primes obtained by inserting/placing a digit in a(2) = 17 are 107,
               127, 137, etc...a(3)= 107 is the smallest.
