Terms a(5) and a(6) were found using a program provided by _Norman Luhn_ during an effort to find A210439(8) and A332493(8). %C A346998 Since this prime constellation leads to the same Hardy-Littlewood constant as for A022011, the expected asymptotic behavior is also the same as in A346996 for large n. See the comment there for more information. Accordingly, the comparison value for a(6) is 1.647755*10^16 and the prediction for a(7) is 3.0824636*10^17. %H A346998 Norman Luhn, <a href="https://pzktupel.de/counting/PI_08.php">Number of 8-tuplets with initial members < 10^n</a>, (2021). %Y A346998 Cf.
