DroneBetter (talk | contribs) Mention jam support (perhaps there should be only a single page for keys variants, if there is nothing to be said about the individual ones and we wouldn't like to duplicate anything) |
formatting // Re: previous edit's summary -- disagree with "nothing to be said". I've just looked at the pages (and their edit histories), and there is already something interesting said about each one. Pages can be further expanded for example by documenting known syntheses. It would be an extra work to decide how to merge everything in a single page and do the merge -- and in my opinion that extra work would not improve anything. |

Short keys is a period-3 oscillator found by Dean Hickerson in August 1989.[1] In August 2004 Jason Summers found a 10-glider synthesis of this oscillator.[2] It can be extended infinitely, like the odd keys. The dot sparks it emits lets the tubs it perturbs act as loafs to support jam.
