%N Beginnings of maximal chains of primes with seven members (six links).
%C For definitions see A152658, of which this is a subsequence.
%e First maximal chain of primes with seven members is 2153, 2161, 2179, 2203, 2207, 2213, 2221; the six linking primes are 1404211, 1417019, 1435117, 1448687, 1456393, 1465441.
