With the help of ljkiernan1, here's another reduction to the p45 gun to 33x24 (792-cell BB) using a PD and a Jam:

Code: Select all

x = 33, y = 21, rule = B3/S23
24bo$23bobo$22bo3bo$22bo3bo$8bo4bo8bo3bo$6b2ob4ob2o6bo3bo$8bo4bo8bo3bo

o$10bo$22bo5b2o$23b2o4bo$22b2o$9b2o$9b2o!

By beating out the p55 gun (928-cell BB), this makes p45 the smallest odd-period glider gun!

Edit: It's even small enough to reduce the p90 gun too! (37x30 (1110-cell BB) to 33x32 (1056-cell BB)):

Code: Select all

x = 33, y = 29, rule = B3/S23

Makes it into a "theoretically nice" edge shooter, too, but it's not clear that this will help build any pseudoperiod guns -- it doesn't seem to be compatible with filling in gaps in a p43 stream.

Check the RLE headers. The total number of cells in the bounding box is the only thing that really matters for "improving" a gun -- could maybe add population as a secondary metric, but that's not currently tracked by Catagolue.

Very nice! I was look forward to a more compact p64 gun, and this one is might be what I was looking for. It seems there is a hershell output too, but annoyingly there is a eater in the way of a common eater in the h-to-X conduits... still one can convert this to a "p128" hershell producer, but I think I managed to find a comparably large way to do this before, but still it might be a better alternative:
