#C This quadratic replicator makes a beautiful fractal by laying
#C or deleting tubs while expanding indefinitely. Give it a couple of
#C minutes in HashLife's Hyperspeed mode, and the resulting pattern 
#C will allow for zooming/magnifying for a few hundreds of times, just
#C like a journey in a professional fractal-rendering program!

#C Similar replicators are also found later, for example bo$3o$bo!

#C (by Jiahao Yu in p131505) in 2021, but both of these are somewhat
