B468/S02357's Bird-brained bibliography of rules

[B468S02357]

Another of my topics, this time my rules. Of course, there's B3/S23|B34/S134, my favorite, and B468/S02357 or scarce life, which i used to think was notable, but now, it just seems like any other rule.
Then, there's this unnamed rule, which has an RRO of loopability 4.

As i golf more, i will put them on a list not unlike FWKnightship's list.

Pretty cool, might be another of my favorite rules

A chaotic variant of your namesake rule with two common speeds (c/10d and c/6o):
