     This is a wierd, non-convex geometrical figure, with nine points evenly spaced from their neighbors.  Although this shape looks quite irregular from many viewpoints, all the edges are actually the same length - measure some to check it out.  View3 shows that the vertices all fall on points in a square grid;  turn on "XYZ point" under the Tools menu and click on vertices to get their coordinates (the central blue vertex is at the origin and all edges = 2.0).
     This arrangement represents the relationships of sequences of length 2 where each position has three possible values.  Those values are shown in the figure by color for position 1 and ball size for position 2.


       ************************************************************
     Can anyone tell us who may have described this figure before, and whether there is a name for it?
