@briansullivan I know! Not holding you responsible. Here's the question I asked before posting:
Me: "Let's say we have a set of integers. What is the name for the property of such a set that says that no one member is bigger than the sum of the other members?"
ChatGPT: "The property you're describing is called the Helly property or Helly's condition for a set of integers. Specifically, this means that no element in the set is greater than or equal to the sum of the other elements in the set. "
