In principle, moderate values should appear infinitely many times, by analogy with twin primes hypothesis. For example, a(n) = 44 for n = 9, 17, 206, 1604467, 12905293, 18008874, 26545460, 32655424, 57848470, 58313630, 59022635, 66275281, 81581956, 123780499, 160884754, 167797255, 179786560, 181569324, 239542290, ... - Zak Seidov, Sep 14 2014, edited by M. F. Hasler, Dec 03 2018

According to the k-tuple conjecture, any admissible k-tuple of primes occurs with calculable nonzero asymptotic density, i.e., in particular, infinitely many times. For k = 11, number of primes in the interval [prime(n), prime(n+10)], the smallest possible diameter of a k-tuple is A008407(11) = 36, and there are A083409(11) = 2 such constellations: {0, 4, 6, 10, 16, 18, 24, 28, 30, 34, 36}, first occurring at A213646(1) = 1418575498573, and {0, 2, 6, 8, 12, 18, 20, 26, 30, 32, 36}, first occurring at A213647(1) = 11. The combined list { prime(n) | a(n) = 36 } is A257129. - M. F. Hasler, Dec 03 2018
