Problem: are there infinitely many such numbers?
From Daniel Suteu, Sep 17 2020: (Start)
If we consider f(n) to be the smallest number in the sequence with n prime factors, then we have:
f(3) = 294409,
f(4) = 3018694485093841,
f(5) <= 521635331852681575100906881,
f(6) <= 2835402730651853232634509813787097410561,
f(7) <= 165784025660216242122027716057592895796242004385542265601. (End)
