### Things to be discovered

Posted:

**March 3rd, 2017, 4:20 pm**Post ideas for CGOL inventions/discoveries here. Maybe you could get some extra people working on it that way. I'll do my best to update the list here.

Mr. Missed Her:

Mr. Missed Her:

- The almost not knightship.
- The 0E0P unit cell, a unit cell for which the off state is a void. 0E0P is a massive contraction of “Off [0] state encoded with zero cells.”
- A “wall” or “shield,” an extendable eater that can eat spaceships/other patterns regardless of it’s positioning/trajectory. Bonus: A way to connect sections at an angle without the corners being vulnerable.
- A “tank,” a spaceship which has “armor” not necessary to the ship’s movement but can absorb gliders and other potentially threatening patterns without sustaining permanent damage.
- A fully working "twitching ants" telegraph. (With or without max bandwidth.)

- A machine that can receive and "store" gliders in a closed loop and release them when given a signal.
- A period ≠2 phoenix.
- A puffer which synthesizes unusual still lifes.
- A non-oscillating heisenburp.

- Non-trivial oscillators of all periods not yet discovered.
- Elementary spaceships of speeds c/8-9o and c/8-11d.
- Elementary knightship, does not neccesarily have to be a derivative of the almost knightship.
- Elementary 1-D and 2-D replicators.

- Period 7 rake.

- Small (<25x25) stable period-changing 90-degree glider reflector
- Small (<25x25) Spartan stable 90-degree glider reflector
- 90-degree elbow for 2c/3 signal wire

(this would probably solve the unknown oscillator periods and prove omniperiodicity) - Double 2c/3 signal to single 2c/3 signal converter

(would also solve the omniperiodicity problem) - Stable small direct G-to-2G

(would make a good fraction of the gun collection obsolete again) - Stable small direct two-state G-to-G switch

(alternate output gliders sent in different directions) - Glider construction recipes for the remaining 16-bit still lifes for which no efficient construction is known
- Glider construction recipe for an edge-repair spaceship

(just to make the Heisenburp detector in the link actually "useful"...) - Explicit N-glider construction recipe for a mechanism that can construct any glider-constructible object, no matter how large, using a fixed number of gliders.
- Complete list of all possible distinct three-glider collisions (different sparks or ash)

(with hashes of each of the ashes, please...) - A seed string for a C1 Catagolue soup that produces a loafer or any new spaceship type
- A freeze-dried waterbear
- A Garden of Eden with fewer than 45 ON cells, or a proof/search results showing that no such object exists
- An orphan with fewer than 88 defined cells, or a proof/search results showing that no such object exists
- A pattern that has great-great-great-grandparents but no great-great-great-great-grandparents
- 4-cell-high Garden of Eden, or proof that this is impossible
- quadratic-growth pattern with fewer than 23 cells
- Compact hot-swappable glider timing adjustment circuits with a continuous range of timings
- Direct reflector for some *WSS (no intermediate B/glider/Herschel/pi/QB/R stage)
- Direct small B/glider/Herschel/pi/QB/R to switch engine (swimmer) converter

[i](swimmers are so slow that this might actually help reduce higher prime-period guns) - Direct small HWSS to B/glider/Herschel/pi/QB/R converter
- Direct small B/glider/Herschel/pi/QB/R to HWSS converter
- Direct small B/glider/Herschel/pi/QB/R to LWSS converter
- Direct small B/glider/Herschel/pi/QB/R to MWSS converter

(no separate signal needed to kill the Annoying Beehive(TM) that usually seems to be inevitable - Direct small B/glider/Herschel/pi/QB/R to switch engine (swimmer) converter

- synthesis of a c/4 orthogonal spaceship
- syntheses of all oscillators up to 16 bits (2 left)
- syntheses of any other new speeds of spaceships
- syntheses of the remaining 20-bit pseudo still-lifes
