Perspective view of a graphic representation of the periodic table of chemical elements consisting of four space lemniscates of varying sizes. This table was originated by Alois Bilecki in 1915 and classified by chemist Edward G. Mazurs as Type IIIA2-2 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This table appears as Figure 64 on page 133 of Mazurs' 1957 publication.</div>
