%N A079018 Suppose p and q = p+16 are primes. Define the difference pattern of (p,
               q) to be the successive differences of the primes in the range p 
               to q. There are 17 possible difference patterns, namely [16], [4,
               12], [6,10], [10,6], [12,4], [4,2,10], [4,6,6], [4,8,4], [6,4,6], 
               [6,6,4], [10,2,4], [4,2,4,6], [4,2,6,4], [4,6,2,4], [6,4,2,4], [4,
               2,4,2,4], [2,2,4,2,4,2]. Sequence gives smallest value of p for each 
               difference pattern, sorted by magnitude.
%e A079018 p=181, q=197 has difference pattern [10,2,4] and {181,191,193,197} is 
               the corresponding consecutive prime 4-tuple.
