For a graph G with n vertices and m edges, the number of vertices of the line graph L(G) is m, and the number of edges of L(G) is half the sum of the squares of the degrees of the vertices in G, minus m. [6] An independent set in L(G) corresponds to a matching in G. In particular, a maximum independent set in L(G) corresponds to maximum ...
Ñ, or ñ (Spanish: eñe, ⓘ), is a letter of the modern Latin alphabet, formed by placing a tilde (also referred to as a virgulilla in Spanish, in order to differentiate it from other diacritics, which are also called tildes) on top of an upper- or lower-case n . [1]
The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.
In mathematics, the general linear group of degree n is the set of n×n invertible matrices, together with the operation of ordinary matrix multiplication.This forms a group, because the product of two invertible matrices is again invertible, and the inverse of an invertible matrix is invertible, with the identity matrix as the identity element of the group.
In mathematics, the term linear function refers to two distinct but related notions: [1]. In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. [2]

The associated extensions SL(n, q) → PSL(n, q) are covering groups of the alternating groups (universal perfect central extensions) for A 4, A 5, by uniqueness of the universal perfect central extension; for L 2 (9) ≅ A 6, the associated extension is a perfect central extension, but not universal: there is a 3-fold covering group.
