We finished sieving SR5 quite a few years ago, so we're not sieving it now, nor do we have any plans to do so again in the foreseeable future..

I don't recall the exact limits, but it was to about 8 or 17 million digits (i.e., roughly n=25M or n=50M for base 2 projects) and was sieved to what would now be double the optimal depth.

The last range sieved was for n=5M to n=10M and 100T. SR5 is only in the low-mid 3M range right now, so we're set for a while.

Time to fix that! :D
