New Long Period Oscillators
Here's another set of miscellaneous long-period oscillators found recently—
A Period 25 Pre-Pulsar Pusher, also found by Summers. The Period 5 Oscillators provide sparks which push the Pre-Pulsar 3 cells in 11 generations, while the stable objects return it in 14 generations.
Another type is a Period 44 Oscillator. Shown here are two ways to suppress the double Pi Heptominoes thrown off every cycle. He suggests that these Pis can be perterbed to produce other objects, including Glider Guns.
