Bent keys is a period-3 oscillator found by Dean Hickerson in August 1989.[1] In September 2004 Jason Summers found a 10-glider synthesis of this oscillator,[2] which was improved to 8 gliders by Jeremy Tan in June 2019.[3] It can be extended infinitely, like the odd keys.
Trans pulsar horn variant
The outer ends can also mutually stabilise an object comprised of two pulsar horns in C2_2 symmetry. Unlike the standard centre, this only works with the odd keys variant.
