There's a fairly small p4 oscillator that can replace the fifth p22 engine in a p44 gun. Is that oscillator any cheaper to construct than the p22, by any chance?

There are a few other p4s that work, but I don't know if they'd be any cheaper to construct:

No, but there's a new mechanism that can make a cheaper gun.
I discovered this
2G-on-the same-lane-seperated-by-22-ticks to "ColorfulGalaxy's MWSS spark" on January 27,
2020. Feed the output of a p22 gun into it and it becomes a p44 sparker. This sparker is able to work as a filter (only one glider lane is accessible!) So it's possible to make a p44 gun out of four p22 (or two p22 guns) and two blocks (used in the filter), at a total of 4*9+3=39G. That's an improvement over 45G! Still worse than 26G of a p48 gun, but keep in mind that p44 is much more likely to raise a working toolkit because it is not divisible by 6, allowing 3 possibilities.
Code: Select all
x = 48, y = 62, rule = B2n3/S23-qHistory

The two blocks can be synthesised within three gliders. Some examples:
Code: Select all
x = 161, y = 26, rule = B2n3/S23-q

Also, in the original mechanism, the extra oscillator is only used for eating a blinker, which probably can be done with a catalyst (although that probably won't help creating an easier-constructible gun). The typical method using the "robust" catalyst fails, there's a spark that interferes with the next glider at the last moment:

x = 40, y = 67, rule = B2n3/S23-qHistory

This should work for p24 though.
(In the corner marked by the red line are the possible space for catalysts.)
