R2F(1/2B) is the R2-Name of the filament that lies on the real axis. It is the largest and most prominent filament, and thus has many colloquial nicknames.
It contains the largest island mu-molecule, R2F(1/2B1)S
The real axis itself, or specifically the line segment from -2.0 to the Feigenbaum Point, comprises a significant portion of R2F(1/2B). A large part of this line segment belongs to mu-molecules, but when these points are removed the result is a Cantor-like set that has positive measure (i.e. it has a non-zero total length).
David Doff has approximated the total length of this chaotic portion of the real axis, by using the method to measure pixels on a line which approaches the real axis asymptotically from above. The grid density and iterations are increased at the same time. The result is 0.55.
