R2F(1/3B*)

Robert P. Munafo, 1999 Feb 2.


R2F(1/3B*) (abbreviated name: RF(3B*) ) is a Branch Point in the filament structure of R2.1/3a :

Three main branches or spokes are clearly visible. They are:

R2F(1/3B0) (which is labeled)

R2F(1/3B1) (which extends to the upper-left)

R2F(1/3B2) (which extends to the upper-right).

One bizarre feature of most branch points is that the branches actually spiral in. As you zoom in towards the branch point, you can see that the angle from which the three branches approach gradually changes:

This spiraling continues forever: Each branch twists an infinite number of times around the branch point.
