Nicolay Beluchenko has found a new type of Period 4 Oscillator which can be used in both wicks and agars. The first line of the illustration shows the first four orders of the wick version, with the last entry showing some alternate ends and sides. The use of Hats [9.1] also allows variable spacing and in some cases for sparks to appear between them. The second line shows how to bound the ends to create agars.
