This appears to be an excellent compilation. I hope it will always be easy to find. Many things here get buried in the mix rapidly.

Thanks. I've scattered bread crumbs (pointers) here and there in the forum. I find it useful to link back to these posts which saves me typing when responding, and may lead people to more. A web browser bookmark to the sub-site map page works too. It grew so big a post or two at a time that I created that for my own use in quickly finding what I knew I had already written.

Sub site map to the reference info, and also discussion threads like this one: https://www.mersenneforum.org/showthread.php?t=24607

While I understand the forum is a good place to discuss such things, much more comfortable than the discussion pages of a wiki, a forum is not a good place to store reference material (except perhaps in closed threads) : it gets buried in the discussion about its elaboration and adjustments.

A suggestion/addition: rather than "squat", nomenclature which has been used previously to describe this is "working `off-the-books`".

Edit: Oh, and also perhaps, add "Wave-back", AKA "Stragglers".

I would suggest that you look at the wiki for other ideas.

Also, miletsones acknowledge DC milestones, proving a prime is the Xth MP, and all exponents tested once up to a given MP

This is precisely why I have collected the materials into a blog space that xyzzy offered me. The dilution by discussion posts here has so far been minimal and manageable. Discussion threads here are only ~2% of the total thread count. Posters are warned elsewhere that discussion posts in reference threads may be moved or removed (deleted) without warning or recourse. In the event that I become unwilling or unable to maintain it at some point, Xyzzy can close all the reference threads. I suppose as moderator of this tree I could close and open them when I edit, but so far it has worked rather well to leave them open.
Anyone with the knowledge and desire to create a GIMPS reference wiki is free to create links to these reference posts. I plan to not do so.

The location of the GIMPS reference posts site map is unlikely to change; bookmark it. https://www.mersenneforum.org/showthread.php?t=24607 It is now book size, with over 200 reference posts.

If you want to overhaul any post in that thread (except the links to M40), a super-mod can take your revised version and sub it in for PrimeMonster's.

Thanks for the invitation. My first reaction is, not at this time. Maybe someday. Meanwhile, I suggest if PrimeMonster is no longer active, appending a pointer link there, over to my reference info here which is being actively maintained and extended, specifically, to https://www.mersenneforum.org/showth...922#post521922

(in reference to https://www.mersenneforum.org/showpo...72&postcount=5)


So why not using my Prime Wiki, the reanimated MersenneWiki with those old data and pages around GIMPS.

Daily backups (holding for two weeks) for the database are set.

Other advantages:
- history of any page edit
- create your own pages naming like you want
- linking to other pages or externals are easy done
- many programs are described in the Wiki but need some updates in information
- many pages for Riesel, Proth, Williams, Carol/Kynea, Leyland primes are currently available and should become more and more holding the history of search spreaded all over the internet (e.g. see Carol/Kynea base 2)
- Math rendering available
- upload/display of PDFs is available

A clear categorizing should be done first for your pages although most of your topics are in the Wiki.
