Constraint violations report for OEIS ID (Discussion, uses, items, changes, related properties): identifier on the On-Line Encyclopedia of Integer Sequences
Data time stamp: 29 April 2024, 11:04 (UTC) — Items processed: 372
The report is generated based on the settings on Property:P829#P2302.
Updates overwrite this page. Some may already be fixed since the last update: check RecentChangesLinked.
When incremental dumps and the bot work as planned, items fixed before 07:00 UTC disappear in the next update. The report is not updated if only the item count changes.
The report can include false positives. There is no need to "fix" them.
