Since time immemorial, there has been a desire to find a c/5 orthogonal anteater. The motivation arises from the existence of a c/4 diagonal antstretcher, which produces a compatible oblique line of ants. By fusing the two components seamlessly, a growing spaceship could be created.
Matthias Merzenich has finally found this long-awaited anteater, enabling completion of the antstretcher.
Eight copies of this can be combined to create another example of a 'space-nonfiller' (a term coined by Jason Summers), the earliest such example being discovered by him in 1999, which expanded at the vacuum speed limit.
At right is a diagram shows what the full pattern looks like, with a sample section of the generating line of cells expanded to explain the mechanism used to construct the breeder. Line sections are arranged to produce exactly-timed two-glider salvos, which collide to produce LWSSes, which in turn collide to build the breeder. A multi-step reaction at the X axis produces the second glider in each pair with an exactly-timed delay relative to the first one.
