Hi all

Just had this email and now I'm in shock !!!!!!!!

Dear Primefinder,

Congratulations!

Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Generalized Fermat Prime Search n=17 Mega (GFN-17-Mega). What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Since you have auto-reporting selected, the following prime was submitted on your behalf:

Added 134963 : 138830036^131072+1 (1067252 digits)

This prime was found on this workunit (see below) which will automatically show as a prime result after verification by the Largest Known Primes Database.

If you have any questions or concerns, please contact us and we will surely resolve any problems.

Once again, congratulations on your find! Thank you for participating in PrimeGrid.

Hi all

If anyone is interested, someone on Brightspace (the MENSA facebook group) has actually used "PHP BCMath" to calculate ALL the digits:

https://gist.github.com/JackWH/79f7d96a ... e93d6d09dc

and then you can view it in all it's wonderfulness !!

I had an idea to have a T-shirt printed with all the numbers on it from start to finish...the downside is that either the T-shirt would be enormous (if a typical 10pt font is used) OR the numbers would be so small as to be almost illegible, so they can fit onto the front and back of a normal sized T-shirt.

Someone calculated that at the standard height and width of a 10pt font (typically 3.53mm x 2mm), it would need 120 pages of A4 (297mm x 210mm) to print the entire sequence (and that assumes no margins).

Scary thought: This *exact* sequence of digits (over a million of them) can also be found somewhere within the numerical number for "Pi"...
