As far as I can tell there are 7 of them.

Since sieving at the c163 of 30450:808 took a while, I would like to get some help on optimizing the parameters.

Thank you in advance.

PS: The siever was gnfs-lasieve4i15e

a. It is normal to "take a while", for a C163.
b. you can not "optimize the parameters" of a poly you already have (I didn't look into the files, but it seems to be a poly, from the extension of the file names). However, you may find a better poly, if you search longer.
c. you can request a poly (better or not than the one you already have, depends on your luck, you may have hit a very good poly already) in the "request polys" thread, here around. Some people have "dedicated" hardware and are able to get very good polys very fast. You just specify the number, and where it is coming from (like "C163 from aliquot xxxxx") and someone may take up the challenge to find the best poly. The "where it comes from" is necessary because we don't try to factor encryption keys for gaming sites, etc.
