I really like the trick of having the usually-suppressed beehive factory in a syringe do the work of stopping the signal in the base loop, so it can be restarted with a different timing.

^^ The part "the usually-suppressed beehive factory" sounds misleading, in that it incorrectly suggests that the device (the beehive factory) would be activated by default but the activation is somehow usually prevented. It's not that the beehive factory is "usually suppressed", instead it's just activated only once per three-and-a-half cycles of the base glider loop, when the pulse divider emits an output pulse that goes to the factory.

Mentioning "signals" feels like another unnecessary distraction, the pattern is a simple gun with very little logic, which can be understood merely in terms of gliders and counting pulses.

The part "the usually-suppressed beehive factory" sounds misleading, in that it incorrectly suggests that the device (the beehive factory) would be activated by default but the activation is somehow usually prevented.

Sorry, I was intending to refer to syringes in general. I don't usually even think about how one of the eaters in a syringe is really just there to prevent a beehive from being created.

So the idea I was trying to get across was that in the absence of that suppressing eater, a beehive factory would indeed be "activated by default", every time a glider comes in to the syringe.

The eater usually prevents that activation, just as you describe... but in these gun patterns, it works to leave off that eater in one syringe, and make use of the factory-made beehive each time that syringe is used.

There's plenty of room in the bottom right to replace the HW volcano with a custom variant (found quickly just now with JLS) to save a couple columns:

Notice that I also replaced the p5 in the quinti-Snark with a pentadecathlon purely for aesthetics.

Edit: here is the p5 domino sparker by itself:

I'm not sure what the current status of p5 domino sparkers is, but it might be useful in some other contexts. It at least reduces the p825 gun, which is just the above gun without the queen bee.

Edit 2: here is a smaller variant of the above p5 HW volcano, as well as two variants of an alternate HW volcano:

These reduce several guns with periods that are multiples of 55.

Heh, I feel like that's slightly too mysterious of a directive, when it looks like it's perfectly possible to move the blocker several cells NWward and save a row or two.

For anyone tempted to submit an "improved" 46x40 pattern to Catagolue -- the blocker is placed on the edge of a 46x43 bounding box, which is the smallest box that contains the spark that happens when the Karel's p15 suppresses the glider:

So even if the blocker is moved to the red location, the gun's correct size would still be 46x43.
