In this paper we study the complexity of the problem of finding a symmetric subset of maximum cardinality among n point in the plane, or in three-dimensional space, and some related problems like the largest repetive or k-repetive subsets. For the maxium-cardinality symmetric subset problem in the plane we obtain an algorithm of complexity 0(n^2+ 1/3 log n).
