Period-90 glider gun is a glider gun with true period 90. This one by Dean Hickerson uses the output of two p30 guns in a period-multiplying reaction.
The smallest known such gun (by bounding box) is comprised of a queen bee shuttle and a unix doubling the period of the period-45 glider gun.[1]
| The former optimal design, uses one queen bee, a Pentadecathlon, and a jam to filter the stream (click above to open LifeViewer) |
