Actually, I already started those P-1s on my machine.
No factor for the first one, second one will complete soon.

You can find out the depth that an exponent has been trial-factored to by doing:

Download the DECOMP.EXE program from
Download the latest version of
unzip # creates the file NOFACTOR.CMP

# Output lines of the form exponent,depth
# for all exponents between exponent1 and exponent2
# Output goes into a file called "nofactor"

decomp -n exponent1 exponent2

For those two exponents, they were both trial-factored to 65 bits.

But as I said, I already started the P-1 for those 2 exponents.
