between each group of 1,000 digits, but there are actually
ONLY THREE blank lines separating them.]

 ******This file should be named pimil10.txt or pimil10.zip*****
 **This etext is officially being released on January 1, 1993.**

 Corrected EDITIONS of our etexts get a new NUMBER, name11.txt.
 VERSIONS based on separate sources get new LETTER, name10a.txt.

 These digits came from Scott Hemphill (see forwarded message).

 The file should fit uncompressed on a 1.44M floppy, is a million
 and a quarter digits of Pi.  We are also working on one billion.
 The tail has also been checked against the 400 million digits we
 have already received from Mr. Kanada of Japan, and we also hope
 to check against the figures we expect from the Chud[n]ovsky Bros.

I computed the digits of pi using Borwein's method. I used a divide-
and-conquer multiply routine, hand coded in 68020 assembly language.
It was capable of multiplying two 1.25+ million digit numbers in about
20 minutes on an HP 9000/370 (a 25MHz 68030?). The computation took a
little over three days, at which point I had the answer in *binary*.
:-(  The binary to decimal conversion was no simple task. 

I checked my results by performing the same calculation to 2.5+ million
digit precision, (9 days) and compared the binaries.  The only independent
check has come from David Bailey, whose results agree with mine to at least
1 million digits (probably.... AND the last 100 digits are the same.)

 *****The Project Gutenberg Etext of the number Pi***** 

 The digits are arranged in groups of 1,000 in an array 
 of five sets of ten digits per line in twenty lines to 
 a screen with four blank lines between groups of 1,000
 so search programs such as LIST can be used to scan in 
 page mode keeping the groups of 1,000 screen centered.
  
 While we cannot guarantee accuracy, these figures have
 been compared on several occasions with others and are
 apparently in agreement.  However, remember that there
 is a possibility of transmission and other errors.
