Re: PotY 2020 Nomination Thread

Another issue is that, as far as I can tell, there's no set end date for voting. Unlike with nominations, I believe there should be a specific date and time when voting should end. The voting period needs to be long enough that infrequent visitors have a chance to vote. Back to my earlier point: alt...

Re: Spaceship Discussion Thread

How did you find that? I found the small 2c/6 tagalong back in 2010 . However, I did not have a way to support multiple copies at the time. Then in 2016 I found this p6 ship which would have solved the problem, except the leading p3 part was too wide. Even using 117P9H3V0 didn't work: x = 33, y = 9...

Since those were from over 6 years ago, I doubt I could find the original input files. I'm sure they weren't anything special. Just a specified symmetry with a few cells set in the center.

It would depend on your compiler. I suggest searching the web for how to use OpenMP with your compiler. If you figure it out, it could be helpful to other users if you post your solution here.

My list of everything up to 34 bits coincides with this, but was missing the first 32-bit one (LWSS + tag-along). Do you remember who found that, or when, or if it has a name?
It's not surprising that you didn't have it. It was found by Hartmut Holzwart a little over a month ago.
