Add p28 block puffer, rename the more volatile "Jack" (that doesn't have a LifeWiki article) to "lightweight other Jack" (being that there is another with that name, that does have a LifeWiki article), include middleweight and heavyweight other Jack (two related objects), some more xp5 names (I began trying to name every combination of named still lifes on a heart but then gave up because there are too many, but I did all pentoads and Silver's/Elkies' p5s, I think), ordered approximately by existing similarity groupings Also, xp5_y3o71e0e17ozo8844kkvc7g0g7cvkk4488ozoll5088og5d0d5go8805llozx1111v17g0g71v1111zy47430347 is "unnamed" in https://conwaylife.com/wiki/Highest_volatility_period_5_oscillators, should it be named or have an article now that it's semi-natural? (Preferably not 128p5) Also perhaps xp5_y13mi2q0q2im3z1v2gmhe2210122ehmg2v1z0ug2q2sggxggs2q2guz11xhqign0ngiqhx11zy11y51, xp5_y925qzy3o44owfnpos448k8zg8gwooo9hwo44oz0101110s77x11zy3252 and xp5_7k04khf3w3fhk40k7ze20228fcwcf82202e (which I think is especially deserving, being small and volatile), which I think were discovered by Charity Engine (having not been in any stdins containing known oscillators apart from their soup occurrences) xp5_y131io84c0c48oi13z350ocxg8sxs8gxco053zwraxhhhy1hhhxarzok036x127x721x630kozy1og93246064239go was in ror_stdin_test, so I'm not sure Also, I have given xp5_2530fhozy48f10ggzy818f0ca4 and xp5_4ac0fhozy48f10ggzy818f0352 the same name because xs13_2530fho and xs13_3hu06a4 have the same name, so upon changing those, change these also I went through all period-5 oscillators in making this, which I think was a good idea, I contributed some more to https://conwaylife.com/wiki/Highest_volatility_period_5_oscillators
