The 420 21-bit period 3 oscillators

All 420 21-bit period 3 oscillators can be synthesized except two. Unfortunately, due to time limitations, only 218 syntheses have been completed so far. The following syntheses have been completed and are shown below:

The following additional syntheses have not yet been completed; all can be synthesized using the same techniques that are used for smaller still-lifes and period-3 oscillators:


The first 49 21-bit period 3 oscillators

21-bit period 3 oscillators 1-49


The second 49 21-bit period 3 oscillators

21-bit period 3 oscillators 50-98


The third 49 21-bit period 3 oscillators

21-bit period 3 oscillators 99-147


The fourth 49 21-bit period 3 oscillators

21-bit period 3 oscillators 148-196


The last 22 21-bit period 3 oscillators

21-bit period 3 oscillators 197-218
