[Howard_Milano]

This part of the forum appears to be discussing and collecting new glider guns up to period 1000. But it's impossible to weed through posts to collect them. Is Dieter and Peter's updated collection from Jason Summers still the "official" repository or is there another place. I'm willing to help organize and maintain such a list.

The collection is currently in catagolue:
https://catagolue.hatsya.com/census/b3s ... ffset=3200
It contains all guns with periods from 14~9999 (I think?), with pseudo-period guns if a true gun hasn't been found yet.

Minor correction: the guntrue tabulation stores the smallest true-period gun for each period by bounding box (e.g guntrue_72 is the smallest true-period 72 gun), while the gun tabulation stores the smallest gun which produces a glider stream of each period, regardless of the period of the mechanism.
