Visualizations of a Recursive Sequence
The recursive sequence defined by is at . The values of the sequence are divided into blocks of values between and and visualized in several ways.
Snapshot 1: plots of each block superposed and scaled to fit the same range.
Snapshot 2: plots of each block at different levels.
Snapshot 3: superimposing the points of each block versus , where . The picture shows a preferred orientation and the points lie on lines.
Snapshot 4: blocks aligned from the left; a maximum of 23 values is shown. Notice that even or odd values lie in the same column.
Snapshot 5: blocks normalized and scaled to fit the same range.
The author conjectures that is possible to generate this sequence with a substitution system of some kind.
