Glimmering Garden
Rulestring 23-a4city6c7c/3-jknr4ity5ijk6i8
Character Chaotic

Glimmering Garden is an isotropic non-totalistic Life-like cellular automaton with Hensel notation B3-jknr4ity5ijk6i8/S23-a4city6c7c. It was devised by GUYTU6J on August 28, 2019.


Still lifes


There are three characteristic common oscillators, of period 240, 28 and 44 respectively. They are all very sparky and thus play an important role in technologies.

Butterfly, a period-44 oscillator
(click above to open LifeViewer)

The period-240 oscillator cloverleaf is the most common oscillator and the second most common object arising from soups, due to the fact that an R-pentomino (or its 2-generation descendant B-heptomino) is a natural predecessor of it. It is also a reflectorless rotating oscillator with ⌘-shaped motion, albeit of loopability 1. It was this oscillator, found in other rules[1], that led to the discovery of Glimmering Garden.
The period-28 oscillator Julia is the third most common oscillator.
The period-44 oscillator butterfly is the fourth most common oscillator. There is a common non-trivial dimer of it as well.

With the discovery of R-pentomino conduits (see below), oscillators of period 37 or above can be constructed. At the time of writing, the periods for which no oscillator is known are 10, 11, 15, 16, 19~27, 29, 31~33, 35.

All 29 distinct two T-ship collisions
(click above to open LifeViewer)

The bullet heptomino is a c/2 orthogonal spaceship. It is the smallest, fastest spaceship as well as the most common object arising from random soups. Its other phase is a t-tetromino plus one dot spark at the back, hence the name T-ship.
There are 29 distinct two T-ship collisions, 19 of which creates nothing, 6 creates a single T-ship (include 4 fly-by deletions), one creates two T-ships, one creates two blinkers. The remaining two is messy.

Apart from said T-ship, a c/4 orthogonal and a 3c/20 orthogonal spaceship have occured in soups as well, though the latter only in higher symmetrys.

FWKnightship constructed engineered spaceships from rake and puffers of simplified speed 4c/11, 8c/17 orthogonal and 7c/46 diagonal.

Linear growths

The rule has abundant rakes, puffers and guns.

The backrake(Catagoluehere)
(click above to open LifeViewer)

The most common linear growth pattern is a 32c/68 orthogonal double T-ship backrake, as shown on the right. It is the basis of many other linear growths, where the output of this backrake are filtered by oscillators or crashed into other objects.

The third most common one is a 14c/92 diagonal puffer (Catagoluehere) whose output is solely Julias.

Various T-ship guns are based on cloverleaf, Julia and butterfly. The smallest and fastest known gun is a true-period p13 T-ship gun, as shown on the left.

Period-37 R-pentomino loop
(click above to open LifeViewer)

Tub, the smallest still life, can act as a good rock. The period-13 gun above is an example. The tub can also catalyse the evolution of R-pentomino/B-heptomino, which enables the construction of period-37 (or above) R-pentomino loop.

Giving off similar century-like sparks, the oscillators cloverleaf, Julia and butterfly are also excellent for signal circuits. For Julia, T-ship 90° reflector, 180° reflector, Heisenburp, demultiplexer and AND gate have been found.
