Graphic representation of the periodic table of chemical elements designed as a series table with sixteen groups. This table was originated by G.M. Murashov in 1949 and and classified by Mazurs as Type IC3-2a in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). This illustration appears as Figure 40 on page 117 of Mazurs' 1957 publication.
