Mango (or cigar or havoc[1]) is an 8-bit still life. It can be seen as a weld of two loaves or of two beehives. It was found in 1971.[2]

Reactions and uses

There is a long-lasting collision between a glider and a mango, discovered in 1971, with one pentadecathlon appearing in the final census.[3]

Mango appears as a transparent object in a sparky SW-2T21 variant discovered in July 2023.[4][5]

In the slmake search program, a 12-cell pseudo still life consisting of a block and a mango is used in the input file to mark where the initial construction elbow is hit by the glider stream.[6]

In several engineered diehards, the lifespan is increased by replacing toads with constellations containing a mango and another still life.[7]

Occurrence

See also: List of common still lifes, Most common objects on Catagolue

Mango is the twelfth most common still life on Adam P. Goucher's Catagolue, being less common than half-bakery but more common than eater 1. Among all still lifes with 8 cells, it is the second most common, being less common than pond but more common than long barge.[8] It is also the sixteenth most common object overall on Catagolue.

Despite having rotational symmetry, the mango is only very slightly more common in rotationally symmetric soups than asymmetric ones.

In Achim Flammenkamp's census, the mango was also ranked twelfth most common, again between the half-bakery and eater 1.[9]

Glider synthesis

Main article: Glider synthesis

All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
