Re: A Friendly Challenge...
- Hi Mark,
I certainly hope to find a 100,000+ digit mf some time this year.
If I do it will be of the form n!2-1. (but I've got to find it and
they are few and far between). I will have finished to 50000 (106620)
by the end of march.
I then plan to proceed to 100,000. This will involve initially
testing around 2000 "most likely" (based on some extremely suspect
maths I have been playing with) candidates followed by the use of
your multisieve to trim down the remaining 48000 candidates to less
than 10,000 which I will then test. (this should take about a year).
I won't be up to the 100,000 digit range for n!11-1 (224000) until the
end of this year.

- I hope to find either a Generalized Woodall or Multifactorial prime with
100000+ digits by the end of the year. Probaby a n!2+1 if a multifactorial.
Ken Davis seems to be moving faster than I.
