• curprev 20:1420:14, 24 August 2025 MrBrain talk contribs 23,376 bytes +6,092 Added a new section for Domain-Restricted BBi. This section includes examples of the flexible notation, which allows for exact values for i, n, and m, or ranges. Illustrates the value of having both versions, which might be better suited to different questions. Also gives a few selected logical and computed results. Tag: Visual edit
