This data is generally nontrivial to compute, but it may or may not be of any use to anyone anymore (including me). The files have a ".m" extension, but they are just text files. Lists are in Mathematica notation (i.e., with curly braces).

• Koyama's table of integer solutions of n = x³ + y³ + z³. I didn't compute this data, but it doesn't seem to be available digitally anywhere else. (I had to OCR from physical copies.) It accompanies my brief survey of known integer solutions.

• The right side of rule 30. This is a list of the rightmost 121 central cells on rows f ^{231t – 1}I for 0 ≤ t ≤ 2¹⁰, where f is the 2-color, range [–1, 1] cellular automaton rule number 30 and I is the row consisting of a single black cell among a background of white cells. It was computed by a Java program and led to my paper on the subject of local nested structure. (See also sequence A094604.)

• An overlap cluster of length 3000. An overlap cluster is a sequence of words in which consecutive words have nontrivial overlap. In this case, the overlap size is 3, and no word pair is used twice. The effect is better seen when aligned.

• Equivalence classes in F₂. These files contain classes of words in the free group on two generators equivalent under the automorphisms of this group. The generators are a and b, and their inverses are denoted A and B. The words listed are limited to those that are both minimal with respect to length in each class and lexicographically first among all their cycles and all permutations of generators. The root word classes are special equivalence classes. See my paper with Bobbe Cooper.
