Conjecture: All types of still-life can appear from a single row of cell. [...] If taken literally, this is disproven by the existence of an unconstructible still life that cannot form in any way, unless present at generation 0. If one modifies the conjecture to "All glider-constructible still live...

[...] Actually, I believe that the first reaction is a transparent catalysis. In the Transparent object s page, it explains that keeper reactions count as transparent. So really there are two reactions because the first is the block keeping one, while the second deletes the extra chaos. I think the...

[...] The block transparently catalyzes twice . I'd argue there's only one transparent catalysis here. The first time it's basically a non-interacting spark created while deleting the block (if the block was present), rather than a transparent catalysis: x = 39, y = 28, rule = TripleLife .F$2.2F$3....

Hey, does anyone know the glider synthesis for a glider? I couldn't find any. A glider synthesis has to be a collision, otherwise it would be impossible to define when the target object is formed / how many generations it takes to complete a synthesis, and one wouldn't know when "rewinding the orig...

Off-topic:
Try to guess (without quoting this post) if i used code tags or pattern tags in this post. (bet you can't (: )

Easy for someone who knows the history of past interactions. And of course off-topic. See reply viewtopic.php?p=184586#p184586

[...] The only difference between the tags is that when you quote the posts, you see which tag they are using. Therefore, it's sort of a private decision about which tag to use. Therefore, there's no point in telling people to use pattern tags instead of code tags, for it changes nothing for the pe...

Is this H-to-X block catalyst known?

well. i discovered something. i just wanted to add it As a rule of thumb, people shouldn't put their own discoveries on the wiki. See LW:NB for details.

A block can catalyze a Herschel and make it release a glider instead of a ship: [...] It's not useless, but it's not new; see https://conwaylife.com/forums/viewtopic.php?p=179527#p179527 for an example use (with a slightly different placement of the block).
