Character Chaotic

LeapLife is an isotropic non-totalistic cellular automaton devised by Hunting in January, 2020. It differs from Conway's Game of Life by two transitions, much like tlife, but is much more stable.

LeapLife ranked eighth in OCA Discovery of the Year 2020. LeapLife billiard tables ranked last in OCA Discovery of the Year 2021. LeapLife is also the third most-searched non-totalistic rule on Catagolue, after Rule X3VI and Snowflakes.

Patterns

Still lives

Because LeapLife added one birth transition and removed one survival transition from Life, all still lives in LeapLife are still lives in Conway's Game of Life, but the reverse is not true. For example, the snake with feather fails in LeapLife.

All still lives up to 12 bits have occurred naturally. The last of them to occur, trans-very long fuse with two tails, appeared in November 2022, in a soup submitted by FWKnightship. Notably, eater 1 and aircraft carrier are significantly more common than they're in Life.

All still lives up to 11 bits have known syntheses. The following (probably outdated) table displays statistics about the costs for strict still lives up to 11 cells. Green indicates a cost lower than one glider per bit; yellow indicates a cost of equal to or more than one glider per bit. Max costs are linked to the corresponding still life.

Oscillators

A variety of oscillators are present in LeapLife, mostly discovered with apgsearch.

Of all alien oscillators, quite a few of them are especially common, shown below.

Most oscillators known before April 2020 can be found in a GitHub repository.

Spaceships

The gliders and xWSSes still work in LeapLife, and there's an additional (2,1)c/8 knightship called the "lepa".

As of October 2022, all spaceships discovered in LeapLife are elementary. The idea of building a Demonoid in LeapLife was brought up several times, but the spaceship itself is not yet completed. The currently known velocities are c/2, c/3, c/4, c/5, 2c/5, c/6, 2c/7, c/12 orthogonal, c/4, c/5,[2] c/6[3] diagonal, and (2,1)c/6,[4] (2,1)c/8 knightwise. A table of completed spaceship searches can be found here.

Very few spaceships in LeapLife have syntheses. Only the lepa, xWSSes and their combinations, and the c/12 orthogonal[5] have been synthesised.

Linear growth patterns

Guns

Very limited gun technologies are known in LeapLife. 2-engine p22-based and p24-based guns are discovered early on. p19-based guns are first constructed by FWKnightship in March 2021 using an XWSS salvo as an over-unity reaction.[6][7] It was quickly superseded by a much smaller design by AbhpzTa, using a sparker-supported 2G-to-3G reaction.[8]

Guns of period p19N, p22N, and p24N for all sufficiently large N are known as well.

Puffers

Puffers in LeapLife are discovered much later than guns, and very few puffers are known as of now.

The first puffer in LeapLife is the c/2 line puffer discovered by FWKnightship; It can be perturbed into rakes and others.

Some puffers of other velocities are known, including a 2c/5 orthogonal blinker puffer, a c/4 diagonal tubstretcher and a c/5 diagonal half-barberstretcher.[9]

Unstable objects and evolutionary sequences

Methuselahs

Due to the nature of the rule, methuselahs in LeapLife are usually much shorter-lived than methuselahs in Life. The first few methuselahs in LeapLife were discovered by enumerating small patterns; The later methuselahs were found by soup-searching. The longest-lived methuselah currently known is one shown below, lasting 944 generations, found by User:Pzq_Alex.

Common evolutionary sequences

A few common evolutionary sequences in Life are common in LeapLife as well, like lumps of muck, bakery and a variant of pi-heptomino. There are also some other sequences known and investigated for a while that are not as common in Life, like the "butterfly sequence" (different from the butterfly sequence in Life).

A census of 8 × 8 soups in LeapLife has been done, similar to the method used in List of common evolutionary sequences[citation needed]. The result is shown below. Note that the predecessor shown here is not necessarily the bottleneck, but instead the last generation before it reaches 12 cells or more.

Catalyses and other reactions

The simplest catalysis that exists in LeapLife and not Life is a block catalysis from the corner, due to the B2n transition. There are also some other catalysts, mostly discovered with a LeapLife hack of dr by wwei23.
