The '''queen bee shuttle''' (or '''basic shuttle'''<ref>{{CiteLexicon|file=lex_b.htm#basicshuttle|name=Basic shuttle|accessdate=June 11, 2009}}</ref>) is a {{period|30}} [[shuttle]] [[oscillator]] in which a [[queen bee]] travels back and forth between two stabilizing ends. The shuttles were originally stabilized against one another in a square of eight shuttles, though there are now a number of known ways to stabilize the ends. Some simpler methods are shown here involving [[block]]s; for a method involving one or two [[eater 1]]'s see [[buckaroo]]. The queen bee shuttle is the basis of all known true period 30 [[gun]]s (including the famous [[Gosper glider gun]]). It was found by [[Bill Gosper]] in {{year|1970}}<ref>{{CiteHickersonOscillators|accessdate=March 14, 2020}}</ref> and was the first period 30 oscillator to be found. In terms of its minimum population of {{cells|20}} [[cell]]s, it is the smallest known oscillator with period greater than 15.<ref>{{cite web|url=http://www.pentadecathlon.com/objects/class2/class2.php?part=1 |title=Class 2 Objects Catalog - Oscillators |accessdate=April 8, 2009}}</ref>

It produces a spark at the blocks that can be used to rephrase a [[blinker]]; two must be used to make a functioning oscillator from this reaction to prevent formation of a deadly traffic light.

==[[List of common oscillators|Commonness]]==
== Isomers ==
The '''cis-queen bee shuttle''' (shown in the infobox) and the '''trans-queen bee shuttle''' (by shifting one block by one cell) are about the 18th and 19th most [[common]] naturally-occurring oscillators in [[Achim Flammenkamp's census]].<ref>{{citeAchim|accessdate=January 15, 2009}}</ref> On [[Catagolue]], it is the most common period 30 oscillator, with all other natural oscillators of that period featuring it in some form.<ref>{{citeCatagolueStats|October 27, 2018}}</ref>
There are two possible [[isomer]]s for the queen bee shuttle; the version shown in the infobox to the right being the "[[trans]]"-version.


==Variations==
=== Cis-queen bee shuttle ===
The '''queen bee loop''' (or '''ouroboros bees'''), another form of the queen bee shuttle that was found in 1970 (also by Bill Gosper), is a closed loop made of four queen bees that clean up each other's [[beehive|beehives]]. It was forgotten about in many sources and independently rediscovered in {{year|2008}} by [[Nicolay Beluchenko]].<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2008/11/new_small_period_oscillators_2.html|title=New Small Period Oscillators|accessdate=June 3, 2009|date=November 23, 2008|author=H. Koenig|publisher=Game of Life News}}</ref> It is also possible to create a partial loop oscillator consisting of two or three queen bees by removing one or two of the queen bees in the loop and placing two stabilizing blocks appropriately.

Year of discovery 1970

The queen bee shuttle (or basic shuttle[1]) can refer to one of two very closely related period-30 shuttle oscillators in which a queen bee travels back and forth between two blocks (see Isomers). It was found by Bill Gosper in 1970[2] and was the first period-30 oscillator to be found. In terms of its minimum population of 20 cells, it is the smallest known oscillator with period greater than 15.[3]

The queen bee shuttle is the basis of Gosper glider gun, the first known and most compact gun in Game of Life.

Isomers

There are two possible isomers for the queen bee shuttle; the version shown in the infobox to the right being the "trans"-version.

Glider synthesis

There are a few 4-glider components that turn any one-sided stabilization of the queen bee, such as a block, into a queen bee shuttle variant, yielding 6-glider syntheses for both common variants. The synthesis of the cis-queen bee shuttle was later reduced to 5 gliders in July 2020,[4] and an alternate 6-glider synthesis of the trans-queen bee shuttle has also been found.[5] An alternate 5-glider synthesis of the cis-queen bee shuttle was found in March 2023.[6][7] The trans-queen bee shuttle was reduced to 5 gliders by Carson Cheng on May 28, 2024.[8]

Variations

The shuttles were originally stabilized against one another in a square of eight shuttles, but many other stabilisations of the queen bee are now known, such as buckaroo (which utilises an eater 1), hectic (which relies on gliders), a thin one (allowing a 20-cell wide footprint with an unnamed catalyst that functions like a BTS), and the thinnest known one (allowing an 18-cell-wide (albeit 25-cell-tall) one using other queen bees), the latter two of which are useful in bounding box reductions.

The queen bee loop (or ouroboros bees), another form of the queen bee shuttle that was found in 1970 (also by Bill Gosper), is a closed loop made of four queen bees that clean up each other's beehives. It was forgotten about in many sources and independently rediscovered in 2008 by Nicolay Beluchenko.[9] It is also possible to create a partial loop oscillator consisting of two or three queen bees by removing one or two of the queen bees in the loop and placing two stabilizing blocks appropriately.

See also: List of common oscillators

The cis-queen bee shuttle and the trans-queen bee shuttle are the 18th and 19th most common naturally-occurring oscillators in Achim Flammenkamp's census.[10] On Catagolue, it is the most common period 30 oscillator, with all other natural oscillators of that period featuring it in some form.[11]

The trans version is about 2% more common than the cis version on Catagolue.

Catagolue has a dedicated badge which will be given out to anyone who discovers a new variant of this oscillator.
