Graphic representation of the periodic table of chemical elements designed in the style F.M. Shemi︠a︡kin (Fedor Mikhaĭlovich), with additional groups and subgroups. This table was originated by A.I. Mashentsev in 1954 and classified by chemist Edward G. Mazurs as a subtype (IC3-1a) of Shemi︠a︡kin's 1932 design in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This illustration appears as Figure 37 on page 114 of Mazurs' 1957 publication.</div>
1954 (Original design), Circa 1957 (Date attributed to slide)
