  1. The percentages in the brackets represent the proportions of self-penetrating structures to all the structures with each dimensionality type. Items in the diagonal are the numbers of self-penetrating structures with a single dimension while items in the off-diagonal represent numbers of self-penetrating structures containing components of two different dimensionalities. Besides these self-penetrating structures with one or two different dimensional components, a complicated twofold structure containing 0D, 1D, and 3D components(COD ID: 4311765) can also be identified by the quotient graph method.
