%N A062571 a(n) = minimum over m of the size of the largest subset of pairwise relatively 
               prime numbers in {m, m+1, m+2, ..., m+n}.

%e A062571 a(5) = 3 because the largest pairwise relatively prime subset of {2,3,
               4,5,6} is of size 3 (e.g. {2,3,5}) and any 5 consecutive integers 
               must contain at least 3 that are relatively prime
