An LLSSS search with raw rule string "xx!!xxxxx/xxxoxxxxx" and arbitrary width for a nonzero period 7 oscillator terminates almost instantly with no results (a few seconds, like 3 rows in). Barring bugs this rules out any finite* period 7 phoenix oscillator (which the wiki's "Phoenix" article sugge...

There exists only one unique rumbling river rotator and excluding longer wicks which it can be derived from it.

How are rumbling rivers defined again?

Edit: nevermind, I misread it as “rotor”
