Hardly can anyone do elementary number theory today without following in
someone's footsteps. Actually what surprises me the most is that the
half-hour of effort that I put towards developing that heuristic isn't far
from the state of the art!
The paper also led me to question the choice of software to resume your search
for primo-factorials. I'm not well versed on the available software for this
task, so I picked up PFGW which I'm a little bit familiar with. But perhaps
Yves Gallot's Proth is better suited to the task?
Regarding the search, I'm up to n = 7139 and no new primes found yet. I'm
hoping I can get to n = 10000 within a week or so.
