CHEBY9 is a 1D interval, [-1,+1], containing 9 nodes and 8 elements.

MESH3D is a 3D tetrahedral mesh using 8 nodes and 6 elements.

RECTANGLE is a 2D rectangular region which has been divided into 3 rows and 4 columns of squares, each then split into two 3-node triangles. The node and element files of this triangulation are converted into a Gmsh msh file describing the same triangulation.
