The language of mathematics has a wide vocabulary of specialist and technical terms. It also has a certain amount of jargon: commonly used phrases which are part of the culture of mathematics, rather than of the subject.
The class of all groups with group homomorphisms as morphisms and function composition as the composition operation forms a large category, Grp. Like Ord , Grp is a concrete category. The category Ab , consisting of all abelian groups and their group homomorphisms, is a full subcategory of Grp , and the prototype of an abelian category .

Marx argued that the economic base substantially determined the cultural and political superstructure of a society.
The unsustainable exponential progression of a classic pyramid scheme in which every member recruits six new people. To sustain the scheme, the 2.2 billion people in the 12th layer would be required to recruit 13.1 billion more people for the 13th layer, even though there are not nearly enough people in the world to achieve that.
The base regularity of a pyramid's base may be classified based on the type of polygon: one example is the star pyramid in which its base is the regular star polygon. [28] The truncated pyramid is a pyramid cut off by a plane; if the truncation plane is parallel to the base of a pyramid, it is called a frustum.
The Pyramid of Capitalist System is a common name of a 1911 American cartoon caricature critical of capitalism, copied from a Russian flyer of c. 1901. [1] [2] The graphic focus is on stratification by social class and economic inequality. [3] [4] The work has been described as "famous", [5] "well-known and widely reproduced". [3]
