This task was particularly oversieved. I tried filtering with 500/480/460/440M raw relations but didn't get smaller matrix :ermm:

This one had me going for a bit. I tracked the number's identity to [url=https://www.mersenneforum.org/showpost.php?p=513189&postcount=1981]here[/url]:[quote]I finally killed the job known as Phi_3(Phi_31(1087)) and resubmitted it as job 1686__9863_3m1.[/quote]Calculations showed that Phi_3(Phi_31(1087)) wasn't an accurate description.

It turned out that, if N = Phi_31(1087) = (1087^31 - 1)/1086, then the number 28450...38633 is PHI_3(N/7248359).

Thanks to [b]jyb[/b], [b]swellman[/b], and [b]RichD[/b] for enlightening me.
