You are only allowed to use the two-glider collisions (and not any two-glider syntheses for the object in question if it only costs two-gliders), reactions that you discovered or independently discovered, and miscellaneous reactions not immediately relevant to glider syntheses. For example, here is a synthesis of a ship that I made using one of the two-glider collisions that makes a domino spark that doesn't die right away:

Code: Select all

x = 23, y = 13, rule = B3/S23

Cost does not matter; instead, the first person to synthesize the object gets to choose the next object for others to synthesize as long as the object isn't too difficult to synthesize. The first object to synthesize shall be the pond.

x = 40, y = 85, rule = B3/S23

Yes (although you could have used the two-glider collision for a blinker). Now you get to choose the next object to synthesize.

I don't think that I will be able to see any posts that you can't see.

Another similar "glider synthesis challenge" (?) might be to find glider constructions for all catalyst variants that were used in some mechanism (oscillator, gun, reflector, conduit, factory, two components welded to each other) that was posted.

There seems to be no easy way to add the block, to construct the "diehard" still life (xs30_354cwmmz65139d543)?

Code: Select all

x = 16, y = 10, rule = B3/S23

Is it even possible to get a block in from that starting still life? My quick looking at it says we need to turn on the blue cell, the red cell can't be on because it destroys the eater, so we need the white cells, but those also go and interact with the rest of the still life.

Code: Select all

x = 20, y = 16, rule = LifeHistory

Edit:
xs30_0mm0e96z345d1d952 has a synthesis which has the block in place but a bun in place of the eater - any way to get from it to the desired one?
