e/Delta set

Information
has gloss	eng: In mathematics, a delta set (or Δ-set) S is a combinatorial object that is useful in the construction and triangulation of topological spaces, and also in the computation of related algebraic invariants of such spaces. A delta set is somewhat more general than a simplicial complex, yet not quite as general as a simplicial set.
