Primo 3.0.6 is artificially capped at 3000 decimal digits. You will
have to look for the 2.3.3 somewhere on the web. /wink-wink/ ... try
the Files section in the xyyxf yahoo group.

I've been curious myself, and ran three of the near-repunit numbers,
and I am still running a couple of XYYX prps. One of the is Greg's if I
am not mistaken, btw. (Ah yes, it is. 2240^87+87^2240, prp4345. Runs
for a week already. Cracked away only 1/12th of the bits.)
