The 1353 fifteen-bit still-lifes

Due to space limitations, these and their syntheses are shown on a separate page.


The 620 fifteen-bit pseudo-still-lifes

Due to space limitations, these and their syntheses are shown on a separate page.


The 29 fifteen-bit period 2 oscillators

The 78 fifteen-bit period 2 pseudo-oscillators

15-bit period 2 pseudo-oscillators


The 1 fifteen-bit period 5 oscillator

15b P5

Pseudo- barber- pole; Flammen- kamp's P5 [28]

The pseudo-barber-pole superficially resembles the whole series of period 2 barber-pole oscillators, but strangely enough, has a period of 5 instead. It forms the basis for a large number of larger period 5 oscillators (and many with periods that are multiples of 5, such as period 10).


The 1 fifteen-bit period 8 oscillator

15b P8

Blocker [6]

The blocker is the smallest oscillator that produces a period 8 diagonal bit spark.


1 easily-constructible fifteen-bit constellation

20b const.

Blinker and 3 blocks (via Bookend) [3]



Other sizes: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 and larger, not quite stable objects.
