Even if the shapes, sizes, and objects are radically different, they will appear as a group if they are close. Refers to the way smaller elements are "assembled" in a composition. Also called "grouping", the principle concerns the effect generated when the collective presence of the set of elements becomes more meaningful than their presence as ...
In mathematics and logic, a collection of objects and morphisms between them that satisfies certain axioms, fundamental to category theory. category theory A branch of mathematics that deals with abstract algebraic structures and relationships between them, providing a unifying framework for various areas of mathematics. causal logic
In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, the same elements can appear multiple times at different positions ...
In natural language and physical science, a physical object or material object (or simply an object or body) is a contiguous collection of matter, within a defined boundary (or surface), that exists in space and time. Usually contrasted with abstract objects and mental objects. [1] [2]
This is a category with a collection of objects A, B, C and collection of morphisms denoted f, g, g ∘ f, and the loops are the identity arrows. This category is typically denoted by a boldface 3 . In mathematics , a category (sometimes called an abstract category to distinguish it from a concrete category ) is a collection of "objects" that ...
The power object of a set A is given by its power set, and the exponential object of the sets A and B is given by the set of all functions from A to B. Set is thus a topos (and in particular cartesian closed and exact in the sense of Barr). Set is not abelian, additive nor preadditive. Every non-empty set is an injective object in Set.

Collectors and dealers may use the word vintage to describe older collectables that are too young to be called antiques, [3] including Art Deco and Art Nouveau items, Carnival and Depression glass, etc. Items which were once everyday objects but may now be collectable, as almost all examples produced have been destroyed or discarded, are called ...
