Adjustable glider loop
From LifeWiki

An adjustable glider loop is an oscillator composed of stable reflectors (as opposed to oscillator-based shuttle loops such as 6 bits and Double X), whose positioning and distances can be adjusted to give new periods.
Below are loops for every period from p43 to p54. For the even periods and period 49, loops using bumpers will yield a smaller population and bounding box. For 4n periods, the bounding boxes could be reduced by removing one glider from the loops and reducing their length by n cells, but then the reflection reactions would no longer be in the same phase at each of the four corners.
An example of a similar loop reduction is shown for the period 54 example, which is the minimum loop length possible for four Snarks.
