audioactive elements

Conway investigated if he could find patterns in the evolution of the sequence and established a list of so-called audioactive elements, referring to the table of chemical elements. Naming e.g. H = 22, he found that this was stable, always repeating itself. U = 3 leads to Pa = 13 which leads to Th = 1113. You can find this table on Evolution of Conway's audioactive elements . In this table on Wolfram Mathworld you can see elements are appearing in the formula of other elements. You can read the original article of Conway on this weird adioactive decay of the elements at decay. The relationships between the elements is displayed at graph.
