Since the soup search results thread is not dedicated to syntheses, this thread will be. To start off, here's Scot's p5 in 27 gliders from this soup:

Code: Select all

**Any new or improved synthesis I know of will eventually make its way into Shinjuku**, so you may want to keep an eye on it from time to time.

Here's a synthesis helpsheet for those who want to assemble their own syntheses. The number above each collision is the number of generations needed to get from the live cells to the marked cells:
