A practical example
Four orders from twelve fictional words
Start with
The included fictional-words.csv has 12 rows, six A and six B, and two blocks of six rows.
Get this result
Four distinct 12-row sequences. Every row appears once; each six-row block stays contiguous; no same-condition run exceeds two. The pack includes four order CSVs, an index, original input, settings and a printable review.
Examples use fictional or synthetic data. Follow this example step by step.
