R2F(1/2(1/3B1)B)    

Robert P. Munafo, 2023 Apr 17.



R2F(1/2(1/3B1)B) is the R2-name for the mu-unit R2.1/2.1/3 and all attached filaments. The largest branch (consisting of R2.1/2F(1/3B1) together with R2F(1/2(1/3B1)B1)) is sometimes called the lightning branch.

R2F(1/2(1/3B)B)

R2F(1/2(1/3B1)B) is the largest filament that exhibits two different orders of rotational symmetry: 2-fold and 3-fold. The 3-fold symmetry results from 1/3, the internal angle of R2.1/2.1/3a; while the 2-fold symmetry comes from the internal angle of R2.1/2a.

This filament contains the 8th and 9th largest islands, which respectively are R2F(1/2(1/3B1)B1)S (the one near the end of the filament) and R2.1/2F(1/3B1)S. Each is the northern member of a pair with a conjugate twin, the twins are R2F(1/2(2/3B1)B1)S and R2.1/2F(2/3B1)S respectively.

Because of their closeness in size, and because they are spaced in roughly symmetrical positions 1/4 and 3/4 of the way out on the filament, R2F(1/2(1/3B1)B) has a particularly asthetic appearance. (See also R2.2/5a).
