Looks like you know exactly what you are talking about
From which we could assume that you are Mr. Pförtner? (the OEIS sequences with your name attached to them are quite fresh, and I assume this is a very actual domain of your interest, and I see you are also the one who proposed the puzzle  this is indeed an interesting puzzle) Last fiddled with by LaurV on 20191113 at 15:33

Largest for me is now 925119207 but I have no other ideas for how to find larger values. I'm just throwing CPUs at it now.

I‘m very embarrassed, but my two results are wrong. The determinants are not correct. I knew that my code had a bug (meanwhile corrected), but I‘m astonished that the online calculator I have used for control yields the same wrong results.

Wow, that is sooooo discouraging. Assuming I am reading this right, not only has the open question been positively surpassed, but it has done so at least twice. While I have only inched forward still staying way below the threshold.
One comforting positive assumption is that since there are no real shortcuts to the solutions, the tiebreaker must be the computing power of the hardwares used rather than the that of people who use them. Or at least that's what I tell myself to keep from feeling like a total idiot.
