This is the 32nd and largest known to date Woodall prime. It is 712818 digits long and enters The Largest Known Primes Database
(http://primes.utm.edu/primes/) ranked 1st for Woodall primes and 25th
overall.
The discovery was made by Stephen Kohlman of Canada using an Intel C2D 6300 @ 1.86 GHz with 1 GB RAM. This computer took a little
over 5 hours and 41 minutes to test using the LLR program. Stephen is a member of Team Canada.

Well done Stephen! As the number is very long it might be easier just to call it the 'Kohlman prime'.
