The 2 twenty-bit period 30 oscillators

20-bit period 30 oscillators

Queen bee shuttle between trans blocks [6] Queen bee shuttle between cis blocks [6]

The Queen bee is extremely versatile. It is a shuttle that flips over every 15 generations, leaving a beehive egg, which must be removed; in both cases above, by a block. The Queen bee forms the basis for the first glider gun ever discovered, as well as many oscillators with periods of 30n.

It can also eat gliders many different ways:


The 2 22-bit period 30 oscillators

Queen bee between block and down close eater [6] Queen bee between block and up close eater [6]


The 2 23-bit period 30 oscillators

23-bit period 30 oscillators

Trans buckaroo; Queen bee between block and down eater [6] Cis buckaroo; Queen bee between block and up eater [6]

In addition to being able to being able to eat gliders in all the same ways a queen bee can, plus several others, the Buckaroo can also naturally reflect gliders 90 degrees, making it useful in constructing glider loops of period 30n.

Queen bee between block and down close integral [8] Queen bee between block and up close integral [8]


The 8 25-bit period 30 oscillators

25-bit period 30 oscillators

Princess bee, Queen bee between cis close eaters [7] Queen bee between block and down close integral w/ hook [9] Queen bee between block and up close integral w/ hook [9] Trans buckaroo w/ integral; Queen bee between block and down integral [8]
Cis buckaroo w/ integral; Queen bee between block and up integral [8] Queen bee between trans close eaters [7] Queen bee between block and down close integral w/ tub [8] Queen bee between block and up close integral w/ tub [8]


7 period 30 oscillators 26 bits and larger

larger period 30 oscillators

Eureka; Four tubs hassling a pulsar [12] Skewed eureka; Four tubs hassling a skewed pulsar [12] Hectic; Four queen bees shuttling 2 gliders [26]
Capped bad gun [10] Two penta- decathlons hassling two blocks [8]
Double eureka [22] Double skewed eureka [33]

The "bad gun" is a an arrangement of two queen bee shuttles that forms a glider gun that doesn't quite work, because the escaping glider hits the right shuttle at the last moment; if it were advanced only 2 more generations, it would have escaped. This is rescued and turned into a period 30 oscillator by eating the glider before the right shuttle returns.



6 period 30 oscillators buildable from 6 gliders

6-glider period 30 oscillators

Queen bee shuttle between trans blocks [6] Queen bee between block and down close eater [6] Trans buckaroo; Queen bee between block and down eater [6]
Queen bee shuttle between cis blocks [6] Queen bee between block and up close eater [6] Cis buckaroo; Queen bee between block and up eater [6]

The Queen bee is extremely versatile. It is a shuttle that flips over every 15 generations, leaving a beehive egg, which must be removed; in both cases above, by a block. The Queen bee forms the basis for the first glider gun ever discovered, as well as many oscillators with periods of 30n.

It can also eat gliders many different ways:

In addition to being able to being able to eat gliders in all the same ways a queen bee can, plus several others, the Buckaroo can also naturally reflect gliders 90 degrees, making it useful in constructing glider loops of period 30n.
