Now I need to investigate the full extent of duplication by checking: 1) How many distinct names have multiple occurrences, 2) What the distribution looks like, and 3) Whether these are true duplicates (identical rows) or variations (same name, different attributes). Let me query for all names with multiple occurrences to see the pattern.",
