Anchor track

Anchor track is a reaction where anchor A turns two dots into anchor B, which subsequently turns anchor A into two dots, repeating in an infinite set of oscillators. The one shown is period 12. However, adding sets of two dots four cells to the right of eachother yields the erratic pattern of 12, 28, 28, 124, 252, 60, 60, 2044, 252, 8188.

A puffer can produce two cells every four generations and yield infinite anchor track.
