M44 poster.

I like this idea! It would finally look like an _interresting_ modern art poster :)

Humm. Or choose the font size so that all digits fill 2 posters. But that would double the (already horrible) price !!

yes, but is it technically feasible ??

For my part, I would be happy with a trick like numbers in base 60 (numbers from 0 to 9, six rainbow colors, Niceee !), artistic effects (3D, tunnel or perspective depth effect with numbers being smaller at the center, -I remember nice labyrinths like this in the paper "jeux et strategie" in France in the 80's, every month you were deeper in the perspective), other artistic effects (art with prime, the way the fractals are represented)...and so on...

my 2 cents.

Maybe we can simply use the Arrow Notation :

M43 :
ll prices are in US dollars.

2^30402457-1 poster shipped to USA = $53.75
2^30402457-1 poster shipped to Canada = $62.25
2^30402457-1 poster shipped to Europe = $68.75

my wife would kill me if I buy 2 of them !!!
if I buy only one and i put it in our sleeping room, I am guaranteed to sleep alone for the next two months at least...

For now. It would not require a large extension of the poster, less than 3 to 4''. Extending the poster also saves on cost as opposed to printing on two posters. I at least think it would be nice to see the first 10M + digit prime printed in its full glory...extending the poster for the next couple primes is not a bad idea, at least until said number is discovered. Plus, writing in another base could be very difficult or confusing to read.

In theory the as-wide-as-needed scheme would simply require the ability to format a document in landscape mode and print on an industrial-size roll-paper printer.

If that is in practice not workable, then I suggest simply divvying the decimal printout into a suitable number of chunks, and printing each chunk in standard poster format. (That would make framing easier, as well, if anyone actually wants to frame such a large piece of "art".)

But I definitely am strongly in favor of settling on a constant font size for future posters (and perhaps redoing several older ones in said size) - say 2-point, which is still (barely) readable up close with the naked eye, to make the size evolution be reflected in the poster surface area. If it winds up covering an entire museum wall, so what? It's basically a vanity project anyway, done strictly for "cool factor." But that describes no small number of historical large works, including, I suspect, things like the great pyramids. Oh, suuuuuuuuure you built it to "do astronomy" (or whatever the official purpose is) ... ;)

Could you give some more details please? M44 doesn't seem so much larger than M43; would it really be that much harder to simply use the same process as always?

Of course, another option would be to shrink the font size (I think it is already size 1). I don't know if printers are capable of handling that though.

Novelty book. Not as easy to frame on the wall though.

I like the idea of fixing the font size and letting the size of the poster increase (including making new posters in this way for the previous M primes). But wouldn't it look nicer if, instead of fixing height or width, we fixed the proportion? Thus M43 would be, say, 1'' narrower and 1.5'' shorter than M44, but about twice as wide and high as M38 (2M digits).

You should also know that the PSI company is right now trying to manufacture the customary poster for M32582657.

(Note I said "trying"...the region of 1 (that's o-n-e) point font is getting, I am told, near impossible...at least for ink on paper... you will all hear shortly (a week maybe?) on whether there has been success)

I hope he is following this thread.
