Ha, I didn't think of that.

I found some time over the last couple of days to do the M36 poster. It's available at my store:

https://www.exatextposters.com/p/the...19-x-13-inches

If you have any problems or the store doesn't show your country as a shipping destination, let me know.

Thx

166,666,666,666,...,666
Your wish is my command, your darkness...


2*7^n-1 is prime for n=1, 2, 4, 5, 14, 24, 29, 36, 46, 80, 474, 1018, 5180, 22581, 41649, 52744, 114564.

Tested to n ~= 150k, I may continue if in the right mood (this is fun! )

Pick your own for printing... hehe (actually, we prefer the last one, it is bigger and divisible by 3 so you can have a convenient digits grouping )

Even better would be 666666 groups of '666' (~2x101690194).

Default M51 Poster Set Shipping

Quick update. I've retooled how I pack the M51 poster set so the dimensions of the box are smaller and it's about 3.5 pounds vs 4.5 pounds. This makes the international shipping a little lower but still I'm sure not what everybody would want. It helps more with my domestic shipping. It's all I can do until I have a 3rd party fulfilling international orders for me.

You may see me raise the price soon - but I'll also lower the shipping by the amount I raised the price. This is so I can offer a free shipping domestically.

Default M51 Book

This is a separate but related topic. Does anybody have thoughts on whether a book containing all the M51 digits would be something good to offer?

I've seen an M50 book for $2500 (not kidding, and their poster version is like $1700). It's 3 or maybe more volumes. Crazy price. Supposedly there was an M50 book published in Japan but I can't find it.

My version would use my "tiny font" style of printing, but maybe closer to 2pt vs my 1.2pt on the poster set. It would be leather bound if possible, something worthy of being a prize possession. it would be around 100 pages I believe. That's 50 sheets printed in duplex. Price? Don't hold me to it just yet but between $99 and $199. Shipping costs should be better but I don't know for sure. It will be heavy.

Was just wondering if anybody has thoughts about it. Thanks in advance.

After that, I'd like to try a single book that contains all 175,000,000 (or so) Mersenne digits. Tricky but wouldn't that be cool?
