Reflectorless rotating oscillators in other rules

Would the following p32 in b37/s23 count, despite the fact that it can't be made p16 by adding any additional copies of itself?

x = 5, y = 5, rule = B37/S23 b3o$b3o$4bo$2b2o$obo! Lewis 19:05, 22 December 2009 (UTC)


No, it wouldn't, for the precise reason that it can't be made into a p16 (or lower) oscillator. You're on the right lines, though. --Calcyman 15:05, 23 December 2009 (UTC)

Definition fine-tuning

The "two-copy" constraint is obviously there to to exclude 180° on-the-spot rotating things like mazing, smiley, and trans-shuttle, or 90° on-the-spot rotating things like blinker and monogram. It seems like this condition could be lax'd, however. Imagine an oscillator which fills some 270° of the space around its center of symmetry, and progresses in 90° turns: wouldn't this be just about as impressiv as a "shorter" rotating oscillator? I suggest requiring at least 90° of empty space around the center of symmetry (which ensures a lack of communication between the "tail" and the "head" of the oscillator).

(For that matter: I can't think of any asymmetric 90° on-the-spot rotating oscillators in Life outside of hasslers/billiard tables, altho some small examples exist in many lifelike rules, say the glider's non-iconic phase in B3/S24.)
