# [Cado-nfs-discuss] DLP in GF(p^2)

Tue Feb 26 12:09:37 CET 2019

```I'm trying to solve DLP in GF(p^2), but I can't understand the meaning of content of the dlog file.

for example, I run
\$ ./cado-nfs.py -dlp -ell 101538509534246169632617439 target=92800609832959449330691138186 191907783019725260605646959711

when I check the dlog file

0 added column 1
1 2 0 rat 11263248339990185810045507
2 2 1 2 12541292681907710540942564
3 2 1 0 26169984000654153206885433
4 3 0 rat 43922029394620212666409206
5 3 1 3 41861160113074041025737154
6 5 0 rat 19122001771036665804449257

.....
this is what I got.
I can see log(2) = 11263248339990185810045507 from the second line.
but what's the meaning of the third line?

the true quesion is when I run
\$ ./cado-nfs.py -dlp 100000000000000000039 -ell 164354743277891 -gfpext 2
I check the dlog file. I got this:

0 2 1 2 1
2 3 1 3 102959394436835
4 5 1 5 141624366326326
6 5 0 4 0
7 7 1 4 65058838932456

10 17 1 14 18157130075680
12 1f 1 14 8740381071634

......
I can't see the meaning of these lines.
I'm looking forward to your reply.
