New Period 4 Oscillators

Olive Olive P4s P4s

Nicolay Beluchenko has discovered a large set of related Period 4 oscillators. They are based on components which can connect to the rotor component he calls the "Olive", shown at right. This component can be connected to other Period 4 oscillators and rotors when one of the right cells outlined in red is active during generation 4n+1, and then when one of the left cells is active in generation 4n+3. Three examples supported by various P4 with suitable sparks are shown.

Also shown are a selection of the new objects reported. Not all of these include the Olive component, but contain components which can be combined with it to produce other oscillators.

Lightspeed Signals
Lightspeed Signals Update

Gabriel Nivasch has updated his webpage on lightspeed signals. These are structures and objects in which a signal propagates faster than the empty space limit of c/2.

New Diagonal c/5 Spaceship

86P5H1V1 Jason Summers has found a new diagonal c/5 spaceship. With a population 86 bits in its smallest phase, it becomes the smallest known example for this speed and direction. It is less than one third the size of the next largest example, which has a population 295 bits.
