The first member of this sequence is currently (Dec 02 2012) one greater than the largest member yet found of cousin sequence A219553. Therein the value of 313 required significant time to determine. This is almost surely a coincidence, though it would be very interesting if it were not.
666 found at x = 72231492 under the iteration of A219960. No more entries up to x = 100400000
