740856 is at index 5824; this is one of the longer sequences now, though it's afflicted with 2^4*31
746564 at 100 digits, 2^4*3^2*5

Reserving 749320, 749640

Was there a pattern to your original reservations? I am plodding up boringly through the numbers, and would like to know whether I'm in a field from which someone else has carefully already removed the foxes ...

No real pattern. I just don't like to take 2³*3*5-s right away and skip them and some other outright dead meat. Yes, of course, they all have a chance to escape, but there are chances and chances.

749640 finished very quickly (100 digits, 2^3*3*5); taking 749682
745212 now at 105 digits, 2^2*7*3^2; taking 749832
