I got the gun synthesis finished!

It uses 55G (5G below my initial target of 60G) to create a stator variant of the p420 gun with one of the capping eaters in a different position:

This is, to my knowledge, the first synthesis of any infinite growth pattern in this rule.
Unfortunately, it is rather complex, and it might be difficult to create a MSM breeder using it.
EDIT: Synthesis for a T tagalong (
xq4_8mnwss8z013) in 16G!

This should be gunnable - the glider salvos are a little tight, especially the top-right one, but
clock insertion works in this rule, so if the 2G inserter (the 2G collision producing a glider perpendicular to both input gliders) fails, I can use that - especially since the clock is more common in this rule and should be easier to synthesise.
The repeat time is, sadly, >420, so we cannot use my small glider gun to create a gun for this, but I will adjust it to p540 and use that as the basis for the T tagalong gun.
