Gabriel's p138 is a period 138 oscillator discovered by Gabriel Nivasch on October 13, 2002. In terms of its 36 cells, it is, by far, the smallest known period 138 oscillator.[1] Within a month of its discovery, Jason Summers found a 12-glider synthesis for this oscillator.[2]
A variant of Gabriel's p138 with blocks.
