Question: What is the simplest rule that is not omniperiodic?

I saw the following synthesis in https://catagolue.hatsya.com/readsynth: x = 0, y = 0, rule = B3/S23 151$168.A$166.2A$167.2A2$150.A.A$151.2A10.A$151.A10.A$162.3A3$157.2A$158.2A$157.A2$164.3A$164.A$165.A2$154.2A$155.2A$154.A! I made the following fast components with it: x = 1534, y = 625, rule = B3/...

HoneyBomb Life is actually explosive. This is the current smallest unbounded growth pattern I'd found: x = 4, y = 4, rule = B2i3/S23 bo$b2o$o2bo$b3o! It has (at least) two seven-cell parents. x = 25, y = 6, rule = B2i3/S23 2bo2$2o18b3o$2b2o18bo$b2o18b2o$24bo! Also, there is this completely unrelate...

I found a way of adding that small component (muzik called it a "crotchet" a few posts up) onto the edge of an appropriate c/3 spaceship, so that entire family of c/3 ships should now have syntheses: x = 53, y = 39, rule = B3/S23 41bo$39b2o$39b2o$41bo$39bo$38b3o$38bo$37b2o$38bo$39bo2bo$43bo$bo38b2o...
