Have there been any attempts to synthesise the trans-version of each of the emulators? None of the synthesis methods used on Catagolue appear to be able to generalize to these, since structures which are out of the way in the cis-version of each emulator end up getting in the way of reactions, and none of these have appeared naturally to any extent due to their static asymmetry.

Inspired by this, I reduced the lightweight emulator synthesis to 16 gliders (from 21 gliders):

I trivially created trans versions of the trans MW and HW emulators on 2020-04-14 and 2021-05-16 respectively (by just flipping the initial still-life), but Catagolue has since improved the initial still-life placements in all four of the both cis and both trans versions over the syntheses I had previously recorded. In both cases, the trans versions are one glider cheaper than the cis versions. Unfortunately, since the LW emulators require totally different methods than the MW and LW ones, it wasn't possible to create a trans LW emulator this way.
