  3. Schreier–Sims algorithm - Wikipedia

    en.wikipedia.org/wiki/Schreier–Sims_algorithm

    The Schreier–Sims algorithm is an algorithm in computational group theory, named after the mathematicians Otto Schreier and Charles Sims.This algorithm can find the order of a finite permutation group, determine whether a given permutation is a member of the group, and other tasks in polynomial time.

  4. Resolvent (Galois theory) - Wikipedia

    en.wikipedia.org/wiki/Resolvent_(Galois_theory)

    In Galois theory, a discipline within the field of abstract algebra, a resolvent for a permutation group G is a polynomial whose coefficients depend polynomially on the coefficients of a given polynomial p and has, roughly speaking, a rational root if and only if the Galois group of p is included in G.

  5. Permutation group - Wikipedia

    en.wikipedia.org/wiki/Permutation_group

    A permutation group is a subgroup of a symmetric group; that is, its elements are permutations of a given set. It is thus a subset of a symmetric group that is closed under composition of permutations, contains the identity permutation, and contains the inverse permutation of each of its elements. [2]

  6. Mathieu group - Wikipedia

    en.wikipedia.org/wiki/Mathieu_group

    They are multiply transitive permutation groups on 11, 12, 22, 23 or 24 objects. They are the first sporadic groups to be discovered. Sometimes the notation M 8, M 9, M 10, M 20, and M 21 is used for related groups (which act on sets of 8, 9, 10, 20, and 21 points, respectively), namely the stabilizers of points in the larger groups. While ...

  7. Galois group - Wikipedia

    en.wikipedia.org/wiki/Galois_group

    In mathematics, in the area of abstract algebra known as Galois theory, the Galois group of a certain type of field extension is a specific group associated with the field extension. The study of field extensions and their relationship to the polynomials that give rise to them via Galois groups is called Galois theory , so named in honor of ...

  8. Group theory - Wikipedia

    en.wikipedia.org/wiki/Group_theory

    See Rubik's Cube group. In abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as rings, fields, and vector spaces, can all be seen as groups endowed with additional operations and axioms. Groups recur throughout ...

  9. Abstract algebra - Wikipedia

    en.wikipedia.org/wiki/Abstract_algebra

    The permutations of the Rubik's Cube form a group, a fundamental concept within abstract algebra.. In mathematics, more specifically algebra, abstract algebra or modern algebra is the study of algebraic structures, which are sets with specific operations acting on their elements. [1]
