Did you know that the smallest oscillator that is completely asymmetric (not even glide) is... (not sure yet)
Tie between caterer, cis-beacon on table, fox, trans-beacon on table, all with population 12.
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

... that the O quad loaf, the most common 28-cell still life, is over 756 times more common than the second most common 28-cell still life?

Did you know that any glider-constructible pattern can be made with at most forty-seven initial cells due to the reverse caber-tosser?
Did you know that although there are no known stable 5x pulse dividers, any glider stream with a constant period can be divided by five?
Did you know that the repeat time of a stable glider reflector has been reduced by over two orders of magnitude since the first was created?
Did you know that stable reflectors were known to exist for over two decades before the first was created?
Did you know that despite MWSSes being larger and about four times as rare as LWSSes, it is easier to convert a glider signal into the former than the latter?
Did you know that despite being over nine times as large as a clock, a pulsar is over 150 times as common and requires less gliders?
Did you know that the fishhook is cheaper (in terms of gliders) than nine more common objects?
Did you know that despite sparks always dying by themselves, it is possible to preserve certain sparks forever using only other sparks of the same type?
Did you know that it is possible to construct patterns that temporarily exhibit cubic growth?

...that despite 22P36 having been known since 1995, one half of it was not generalized to a versatile three-quarters traffic light catalyst until 26 years later?
...that Merzenich's p64 and 32P21 are both hassling two beehives and two R-pentominoes, and 56P27 are hassling four of each?
...that the smallest periodic pattern by population that is isotropically endemic to Life consists of a p196 pi-heptomino hassler and a pentadecathlon?
...that the extra transition of Pedestrian Life (B38/S23) from Life leads to several non-pedestrian linear growth patterns, including a reflectorless rotating glider gun, a set of (5,2)c/190 technology and a messy oblique p1884 puffer?
...that there are two unrelated composite Herschel conduits with systematic label L156 and repeat time 62 ticks? (The first one consists of HLx69R, RF28B and BFx59H, whereas the second one consists of HL75P, PF35W and WFx46H, but for brevity they need not to be listed in the entry.)
EDIT one day later: thanks to dvgrn who has just added these!
Why do most natural OCA rules tend to get a diminishing span of interest and go into oblivion, like a lost civilization leaving little records for its beauty and power?

I have been focusing on this rule, now in industrial era:

One month has passed so a new post for two issues:
LifeWiki:Did_you_know/56&oldid=61721 and LifeWiki:Did_you_know/96&oldid=50601 conflict subtly and may be outdated.
LifeWiki:Did_you_know/154&oldid=103010 is more or less a duplicate of LifeWiki:Did_you_know/100&oldid=62073, and the same topic (stable glider reflector) has LifeWiki:Did_you_know/18&oldid=35847 and LifeWiki:Did_you_know/155&oldid=103011 as well which seems a bit too many.
Also, the DYK column on the wiki main page is significantly longer than other sections - maybe we can display less items, or make it wider?

I don't see a conflict there. The 0E0P was made public on 12 November 2018, enabling an infinite series of (ridiculously huge and un-runnable) strictly volatile oscillators that are powers of its period... whereas the first infinite series of Golly-verifiable strictly volatile oscillators didn't show up until 21 November.

I did change "3506909" to "3506905", but it was technically true before the change too...!

Yup, #154 was just a less-specific version of #100. I've replaced it with some 2022 news (Game of Life Fun's gliderless GGG puffer).
