Enter a 10 digit phone number into a search string.  With a large enough PI data set, you will locate that sequence.  Thanks to "Person of Interest" TV series for that tidbit of info.  I have tried every person I know, I found there phone numbers in the data set.

Another tidbit.  Prime95 program has a torture benchmark, using PI calculation.  Multi-threaded.
PS.  Don't run long on an under-cooled PC CPU.

Well that's a great idea for some fun! How many digits does it take to get to your phone number?

I wonder if mine is in the first 1000 of p$

Nope! nor the 4 digit, nor the 3 digit! The 3 digit had a very good change I think. Now I am wondering about digit counts in Pi.

I am not sure if prime95 has a number dump function, could have been another.  My PH# was found somewhere around 34k in.  A recent publication of 1 Billion digit of PI was released last year.  Some YouTuber (math nut).  Purchased a physical copy.  The pile was taller that he was.  To get to 1 billion or was it 100 Billion took a PC running over 1 year to complete.  It became a record.  NIST, (yea those guys) consider the use of PI to be a NIST standard, needing publication.

Now that I think about it, prime95 is for factoring prime numbers.  Whoop's.  There are a number of torture benchmarks using PI calculation.  Really gets the electrons flowing. And can cook your CPU.  Prime95 is for over-clockers to test the stability of the system.

But I do stand by my tidbit about your phone number in PI.
