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]
Occurrence
- See also: List of common still lifes
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.[3] It is also the sixteenth most common object overall on Catagolue.
In Achim Flammenkamp's census, the mango was also ranked twelfth most common, again between the half-bakery and eater 1.[4]
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.
Uses
Mango appears as a transparent object in a sparky SW-2T21 variant discovered in July 2023.[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 costellations containing a mango and another still life.[7]
