%N First prime in set of 4 palindromic primes in arithmetic progression ordered by the largest term in the progression.

%C This sequence is a subsequence of A002385, the palindromic primes.

%C The list is ordered based on the highest member of the arithmetic progression.

%C Some primes generate multiple progressions for different common differences.

%e a(2) = p = 10301 is in the sequence because with a distance of d = 3030, [p, p + d, p + 2d, p + 3d] = [10301, 13331, 16361, 19391] all are in arithmetic progression and are palindromic.

%Y Cf. A002385.
