No. It's a guide that does tend to persist, however. The driver is 2^5 * 3 * 7.

The good news here is that you kicked the 2^2 * 7 driver!

~950 iterations and two downdriver runs (+ one escape from 2^4*31) added to the DB.

current status: i=2876; sz. 103; 2^4*5

edit: now at i=2882 with the 2^2 guide.

oops - I accidenty posted my update on sequence 72210 there - just recognized that this sequence still belongs to the subproject.
