## Close Triples of Points

### Description

Low-level function to find all close triples of points.

### Arguments

`X` | Point pattern (object of class `"ppp"` or `"pp3"`).
`rmax` | Maximum distance between each pair of points in a triple.

### Details

This low-level function finds all triples of points in a point pattern in which each pair lies closer than `rmax`.

### Value

A data frame with columns `i,j,k` giving the indices of the points in each triple, and a column `diam` giving the diameter (maximum pairwise distance) in the triple.
