Bill Gosper's link led me eventually to Stephen Wolfram's web age about the "Rule 30" prizes. https://writings.stephenwolfram.com/2019/10/announcing-the-rule-30-prizes/ In that page there is a section that begins like this: "Here’s something else, that may be confusing, or may be helpful. The Rule 30 Prize Problems all concern rule 30 running in an infinite array of cells. But what if one considers just *n* cells <https://www.wolframscience.com/nks/p255--systems-of-limited-size-and-class-2-behavior/>, say with the periodic boundary conditions (i.e. taking the right neighbor of the rightmost cell to be the leftmost cell, and vice versa)? There are 2^ *n* possible total states of the system—and one can draw a state transition diagram <https://www.wolframscience.com/nks/notes-6-7--state-networks-for-systems-of-limited-size/> that shows which state evolves to which other. Here’s the diagram for *n* = 5: ..." Me: So take a cylinder of perimeter n, say Z/nZ X N, turn some cells ON in the top ring, and run Rule 30. What is the max period? Is this in the OEIS?
