In general, an action of a finite group G in a finite set, is described as an application of the group G in the symmetric group Sym(Ω). In this work we will describe some algorithms for permutation groups and implement them in the GAP system. We begin by describing a way of representing groups in computers, we calculate orbits, stabilizers in the basic form and by means of Schreier’s vectors. Later we make algorithms to work with primitive and transitive groups, thus arriving at the concept of BSGS, base and strong generator set, for permutation groups with the algorithm SCHREIERSIMS. In the end we work with group homomorphisms, we find the elements of a group through backtrack searches. / O Teorema de Cayley nos permite representar um grupo finito como grupo de permutações de um conjunto finito de pontos. De forma geral, uma ação de um grupo finito G em um conjunto finito Ω, é descrita como uma aplicação do grupo G no grupo simétrico Sym(Ω). Neste trabalho vamos descrever alguns algoritmos para grupos de permutação e implementa-los no sistema GAP. Começamos descrevendo uma maneira de representar grupos em computadores, calculamos órbitas, estabilizadores na forma básica e por meio de vetores de Schreier. Posteriormente fazemos algoritmos para trabalhar com grupos transitivos e primitivos, chegando assim ao conceito de, base e conjunto gerador forte (BSGS) para grupos de permutação finitos com o algoritmo SCHREIER-SIMS. No final trabalhamos com homomorfismos de grupos e encontramos os elementos de um grupo mediante pesquisas backtrack.
