Update:
On 9/6, NSIDC SIA fell to 3.2 million sq km...this puts 2022 slightly below 2018's 3.23 million sq km minimum. The low concentration ice near the pole has yet to refreeze which allowed the losses on the periphery to add up enough to pass 2018.
The next one on the list is 2021 which had a min of 3.16 million sq km.
As for extent, the NSIDC extent is currently at 4.85 million sq km. We'll see how much lower this goes in the next few days...we haven't had a min above 4.8 million sq km since 2014 (though last year was close at 4.72 million sq km). My guess is we drop below 4.8 million sq km and perhaps below last year as well, but no guarantees.
