Unix [6] |

The Unix is the smallest oscillator that produces a period 6 diagonal bit spark.

Up beacon on up candel- frobra [13] | Up beacon on down candel- frobra [13] | Down beacon on down candel- frobra [13] | Down beacon on up candel- frobra [13] |

All of these have a pseudo-period of 6, a composite of 2 and 3.

All of these except the Blonker have a pseudo-period of 6, a composite of 2 and 3.

All of these have a pseudo-period of 6, a composite of 2 and 3.

Unfortunately, due to time limitations, these cannot yet be shown. These consist of:

- 2 Unix on table.
- 16 Candelfrobra on period 2 oscillator.
- 6 Cuphook on period 2 oscillator.
- 16 Cuphook w/tail on period 2 oscillator.
- 3 Eater eating period 2 oscillator.

All of these except Unix on table have a pseudo-period of 6, a composite of 2 and 3.

All of these are easy to synthesize using standard techniques.

Unfortunately, due to time limitations, these cannot yet be shown. These consist of:

- 16 Candelfrobra on period 2 oscillator.
- 12 Cuphook on period 2 oscillator.
- 32 Cuphook w/tail on period 2 oscillator.
- 9 Eater eating period 2 oscillator.
- 2 Miscellaneous (see below).

All of these except the two below have a pseudo-period of 6, a composite of 2 and 3.

Syntheses for 2 of these (1 still unknown) are shown; all the others are easy to synthesize using standard techniques.

P6 w/ block and head [x] | Nicolay Belu- chenko's P6 between two eaters [24] |

Unfortunately, due to time limitations, these cannot yet be shown. These consist of:

- 6 Unix on cap or long bookend.
- 75 Candelfrobra on period 2 oscillator.
- 22 Cuphook on period 2 oscillator.
- 60 Cuphook w/tail on period 2 oscillator.
- 18 Eater eating period 2 oscillator.
- 2 Jam on griddle.
- 3 Miscellaneous (see below).

All of these except the first and last categories have a pseudo-period of 6, a composite of 2 and 3.

Syntheses for 3 of these (2 still unknown) are shown; all the others are easy to synthesize using standard techniques.

Four blinkers around four blocks [12] | P6 w/ boat and head [x+6] | P6 w/ block and tub [x+5] |

There are several hundred 25-bit period 6 oscillators. Unfortunately, these have not yet been counted. Most consist of combinations of existing components.

Syntheses for 8 of these (6 still unknown) are shown; all the others should be easy to synthesize using standard techniques.

The last two have a pseudo-period of 6, a composite of 2 and 3.

Extremely impressive is an unusual oscillator. It appears at first glance to be a billiard table, but isn't really, as one of the sides temporarily falls apart, but then re-forms later.

Unix [6] |

The Unix is the smallest oscillator that produces a period 6 diagonal bit spark.

Up beacon on cuphook w/ pre-block [21] |

This has a pseudo-period of 6, a composite of 2 and 3.

Blonker [25] |

These are all derived from one base 23-bit oscillator.

Unix [6] (1.7e9) |

The Unix is the smallest oscillator that produces a period 6 diagonal bit spark.
