Raster plot showing a robust heteroclinic attractor in a system of five globally coupled phase oscillators (32) with phase interaction function (45) and a particular choice of parameters (see text). The vertical dark lines mark times (t in horizontal axis) when the oscillator represented by \(\theta_{k}(t)\) (k in vertical axis) passes through zero. Observe that most of the time there are three clusters. Occasionally the clustering splits and reforms different three clusters reforms, at times indicated by the grey bars, approximately every 70 time units. (Adapted from [252])
