Bent keys is a period3 oscillator found by Dean Hickerson in August 1989.^{[1]} In September 2004 Jason Summers found a 10glider 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.
