I have access to quite a few different FPGAs, and would happily provide them to anyone that wants to develop such a thing for trial factoring or prime searching.

Happy to donate a few hundred of...

Well you found one of my errors - I was glancing through the spec sheet and jotted down the marketing “logic cells” value rather than the LUTs for the VU9P. That certainly reduces the advantage a...

You are correct that the routing kills utilization. In smaller chips it can be as bad as 50% due to routing overhead.

The LUT counts actually came from estimating/interpolating off of around page...

1. Was my biggest concern. Regarding 3, at a large enough scale don't statistics take care of this?

I’ve always liked the idea that the only reason prime patterns seem so random to us is our obsession with representing numbers with truly arbitrary bases.
