A lone dot agar is an agar in which every live cell is isolated in every generation. There are many different lone dot agars; all of them are phoenixes. In 1995, Dean Hickerson and Alan W. Hensel found stabilizations for finite patches of ten lone dot agars to create period-2oscillators. One of these (a tiling of 8*8 squares) is shown below:

There is a simpler one also, of 6*6 squares, of which a finite non-extensible stabilisation with components of the Lei appeared in a C4_4 soup in Catagolue.
