Yes. Exactly!
OK. That PDF shows the smallest LUT count for the full pcadd(), as

The earlier statement is inconsistent because I used the source code with
error.
So, the right results are those reported recently.
Here's what I think we should start doing:

Sounds great!
I created the wiki page you suggested and uploaded the 8 files (sources +
pdfs) of bflike.
Please, take a look and tell me if everything is right or not.
Thank you!
