Here is the Golly rule tree for rule B1S235F23K4L035:

<snip RULE>

Thank you Brian. I also like your variant, B1S235F23K4L0, particularly the last gun in the post introducing the rule - the natural guns are more common then with L3 (the L5 doesn't make a big difference) but the still life production is not as diverse. Interestingly, the block is stable in both rules but never seems to occur naturally.

I have explored B1S235F23K4L035 a little more in Golly and there are very occasionally natural guns produced within the chaos:

`x = 7, y = 13, rule = B1S235F23K4L035`

2.B!

More commonly, there is a natural c/2 chaotic puffer:

`x = 7, y = 7, rule = B1S235F23K4L035`

5.BA$5.2B$.B.A.2B$5.BA$.3B$4B$A2BA!

And a few constructed guns:

`x = 26, y = 27, rule = B1S235F23K4L035`

There is also a (rare) natural c/3 ship with p6:

`x = 3, y = 4, rule = B1S235F23K4L035`

BA$ABA$A2B$.2B!

Discovering this led me to another 2c/6 ship composed of two copies of the 6c/18 ship (which also works in B1S235F23K4L0):

`x = 2, y = 7, rule = B1S235F23K4L035`

A$2B$BA2$BA$2B$A!

And seeing the potential, I stumbled on this reaction:

`x = 2, y = 7, rule = B1S235F23K4L035`

AB$2B$.A2$.A$2B$AB!

I'm not even sure how to describe it. It is a clean puffer which moves orthogonally at 2c/17 with p34. To the front it shoots two 6c/18 ships, and to the back it shoots a single 2c/6 ship.

It can be synthesized with two c/2 ships + tagalongs:

`x = 6, y = 11, rule = B1S235F23K4L035`
