Arrangement of Elements 7th Order & Element Sequences

An exploration of some mathematics underlying the periodic table, read the PDF here, by Olivier Joseph.

Oliver says:

"May I propose you the following pattern, as the result of a personal study concerning the arrangement of the Elements, including sequences. Based on some hypothesis and as depicted in the enclosed illustrations, the elements are positioned according to a spiral function of atomic number and atomic mass, representation in 2D in a spiral form pattern, or in 3D conical helix model.

"The elements are numbered and placed consecutively along this spiral according to a specific angle, appropriately established between each element, forming a seven arm spiral pattern. With such an angle, specifically defined, a link is established between the various elements of a same group (corresponding to chemical elements with similar properties) and different layers. These latter becoming distributed among each arm of the spiral in a notable arranged way."
