After a 10-month dry spell, another Fermat factor was finally discovered:
On November 27, 2025, Gary Gostin succeeded in showing that
36812439837 · 23144 + 1 divides F3135.
In this case the difference  n − m  is among the largest ones currently known.

Just under a week later, luck struck once again:
On December 3, Sascha Beat Dinkel and PrimeGrid revealed the divisibility
1085 · 23943263 + 1 divides F3943261.
