Not a big deal, but I moved it for you.

Sequence 72210 has crossed the mark of 3000 iterations (currently at i=3031) and is still just barely part of the subproject - it was just below 110 digits two times.

current status: i=3032, sz. 105, 2^3 (just lost the downdriver

)

Done with:
71016: i1056 (size 110) = 2^2 · 5 · 7 · 29 · 499 · 5471 · c100
71028: i1585 (size 114) = 2^6 · 3 · 11 · 33403 · c106
71052: i1046 (size 112) = 2^2 · 3 · 7^2 · 53 · 139 · 331 · c103
71256: i1616 (size 111) = 2^2 · 7 · 23 · 2593 · c105
71604: i1255 (size 119) = 2^5 · 3^3 · 5^2 · 150279889987 · c103

71028 bounced around between 103 and 104 digits for ages, losing and re-acquiring a driver several times, and then again a few times around 107/108 digits.

71604 also lost the driver many times, at one point decreasing from 107 to 90 digits, so I kept running it a little longer, but now it's at 119.

Reserving 72492, 72708, 72744, 72756, 72800.

Done with 76920 and 76972, taking 75810.

sequence 72210 is at i=3111, sz. 115; stable with 2^2.

It is done for the subproject, but hence it has no driver, I will keep it reserved.
