# Larger Neighbor

Robert P. Munafo, 2012 Apr 16.

A "larger neighbor" of a mu-atom is another mu-atom that is larger (has lower period). There are at most two; one in the clockwise direction and one counterclockwise. (By contrast, there are aleph-0 smaller neighbors in each direction).

If A and B are the larger neighbors of C, then C is the inner neighbor is A and B.

Example: R2.2/5a is a mu-atom. Its two larger neighbors are R2.1/2a and R2.1/3a.

More examples:

*various mu-atoms, some of which are neighbors*

Near the center of the figure is R2.3/8a. To the left (the counterclockwise direction) we see two of its neighbors, R2.2/5a and R2.5/13a. The larger one of these, R2.2/5a, is a "larger neighbor" of R2.3/8a because it is a neighbor and it is larger.

Similarly, to the right (the clockwise direction) of R2.3/8a we find R2.4/11a and R2.1/3a. The first of these is a smaller neighbor and the other is a larger neighbor.
