Dart is an orthogonal c/3 spaceship that was found by David Bell in May 1992. It is currently the smallest known bilaterally symmetric c/3 spaceship, being slightly smaller than the turtle.
History
In December 2014, Martin Grant found a 72-glider synthesis of this spaceship based on components from Dave Greene and Ivan Fomichev, making it the first spaceship of this speed with a known synthesis.[1] Later the synthesis was reduced to 25 gliders.[2]
Everything surrounding the dart synthesis and gun creation was very collaborative. After the first 72 synthesis found by Martin Grant, Chris Cain found a reduction to 62 gliders. P448 dart gun was created by Michael Simkin based on Martin Grant synthesis. Followed another major reduction to 39 gliders by Martin Grant. Michael Simkin suggested a different way to synthesize the tail, while Kazyan found a particular way to reduce the synthesis to 35 glider using Michael Simkin's method. Chris Cain suggested a way to reduce the front synthesis, while Michael Simkin found a particular way implement the idea and reduce the synthesis to 28 gliders. Meanwhile Ivan Fomichev found a tricky way to save two gliders in Kazyan's recipe for the tail, bringing the total to 26. Finally Michael Simkin found a way to reduce another glider from the front making the best known synthesis for today from 25 gliders.
After that, few attempts were done to make dart gun. The first p160 gun was made by Martin Grant, while Alexey Nigin made smaller p210 gun. Then two more guns were made, one by Michael Simkin, the other (smaller one) by Dave Greene. Finally Chris Cain made the smallest p160 gun known today.
