Platonic Sovereign Number is defined by Plato as 604, or 12,960,000. Plato states that "every field of human conduct or investigation may be mathematically modelled."
In Platonic Harmonics, the Sovereign Number is "an arbitrary terminus for the potentially endless generation of tone-numbers, a limitation which [sic.] provides integer expressions for some set of ratios."
Plato created mathematical constructs and used them to model "souls, cities, and the planetary system." Plato did not explain his mathematical allegories, he challenged his followers to find the occurrences of his constructs in nature. The Platonic Sovereign Number demonstrates that Plato had some unstated knowledge of physics, because the number is divisible by harmonics of Planck's Constant, Planck Length, and the Planck Mass at the same time, to one decimal place.
