Robert P. Munafo, 2002 Apr 18.
As you proceed along the real axis. starting at the continent seed R2a and moving through R2.1/2a, R2.1/2.1/2a and so on, the period of the iterates of your current point keeps doubling. Within R2a the period is 1, within R2.1/2a the period is 2, within R2.1/2.1/2a the period is 4, and so on.
