Thanks to some enhancements from George and myself you can see that the next
release of PFGW will not require the -a switch for GFN factoring. You will also
see that it will take a lot less time to test certain numbers. I hope to get a
new release out this week.

pfgw -gxo -q63*2^1070449+1
PFGW Version 3.1.0 for Windows [FFT v25.11]

63*2^1070449+1 is a Factor of xGF(1070447,7,4)!!!! (2991.015000 seconds)
63*2^1070449+1 is a Factor of xGF(1070447,9,8)!!!! (3051.266000 seconds)

Enjoy,
Mark

in a build that I have, but it isn't finding the xGFs either. I need to look
into it further.
