Structure of the experimental test Six simple invariant surfaces (the helix is neglected because is less relevant for the paper’s scope) are illustrated in Table II, with their characteristics.

The original size of the sampled set is about two thousand points, but subsets of different size are randomly extracted and analyzed. 4.2. Results of the experimental test The paper focuses its analysis on classes of symmetry which have not been tested in other works. The analysis of spherical, cylindrical and complex surfaces, already tested in [Chiabert et al., 2001], is limited to a brief summary while major attention is reserved to planar, axi...
