This data file contains tests for a particular edge case that occurs in collaborative text editing CRDTs: in some algorithms, when strings of characters are concurrently inserted at the same position, insertions by different collaborators are interleaved. The code in this repository demonstrates such interleaving occurring in the Logoot, SOCT2, and LSEQ algorithms. No interleaving is found in RGA, WOOT, WOOTH or WOOTO.
