FORMULA
a(n) = prime(A098213(n)). See explanations at A098213.
EXAMPLE
n=7: prime list = {2551,2557,2579,2591,2593,2609,2617},
consecutive differences = {6,22,12,2,16,8};
7 X 7 matrix = [{Abs[p(i)-p(j)]],
C[7,2] = 21 distinct positive matrix entries:
{2,6,8,12,14,16,18,22,24,26,28,30,34,36,38,40,42,52,58,60,66}.
