I want to know the answer to the following question:
What group defined a list of 82 official Apline summits that reach 4,000m?
All the background I'm provided with is that "The Union Internationale des Associations d'Alpinisme (UIAA) has defined a list of 82 "official" Alpine summits that reach at least 4,000 m (13,123 ft).". Is that enough to answer the question?
