👉 In mathematics, an unfulfillable set is a special type of finite set that cannot be represented as a union of two or more non-empty proper subsets. This property arises in algebraic geometry and topology, particularly in the context of simplicial complexes. An unfulfillable set can be defined as follows: 1. A set S is unfulfillable if it cannot be written as the union of any finite number of proper subsets. 2. For instance, a set with 3 elements that
