If a reduced quartic equation x^4 + ax^2 + bx + c = 0 has two positive and two negative roots, there is a simple procedure for generating 24 points in the Cartesian plane, the positions of which depend solely on the roots. These points are not randomly scattered but are arranged in 6 equal circles with a radius R that depends exclusively on the coefficients a, b, c. Behind this unexpectedly complex and organized structure lie geometric methods for solving the quartic equation that had remained unknown until now.
