Graphic representation of the periodic table of chemical elements designed as a series table with eight groups and three subgroups in which the rare earth elements are placed in one series. This table was originated by chemist Edward G. Mazurs in 1955 and and classified by Mazurs as Type IC3-2 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This illustration appears as Figure 39 on page 117 of Mazurs' 1957 publication.</div>
