Oscillators
More Period 4 Wicks

New P4 Wick Element New P4 Oscillators by N.Elkies and N.Beluchenko New P4 Wicks by N.Elkies and N.Beluchenko Noam Elkies has found a new Period 4 wick element, along with a way to stabilize it into an oscillator. Nicolay Beluchenko came up with some other stabilizations, which allowed for elements to alternate along their central spine.

(A similar, inside corner element is not known.)

Oscillators
New Period 4 Wick Oscillators

New P4 Wick Element New P4 Oscillators by A.Dergachev New P4 Wicks by A.Dergachev Artem Dergachev has found two new classes of Period 4 wicks, along with a stabilizations for them. The first wick element can be placed together in two different orientations, as shown in the samples. The first few orders of the homogeneous wick (with all connections the same) is also given.
