Graphic representation of the periodic table of chemical elements designed as a left-step table with Group 0 positioned on the right-hand side of the table. This table was originated by Henry Bassett in 1892 and classified by chemist Edward G. Mazurs as Type IIIC3-1 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This table appears as Figure 68 on page 135 of Mazurs' 1957 publication.
