Results of symmetric groups Sn (n≤7) acting on unordered triples and ordered quadruples
In this paper, we examined the results of fixed point set of symmetric groups Sn (n≤7) acting on X (3) and X [4]. In order to find the fixed point set| fix (g) | of these permutation groups, we used the method developed by Higman (1970) to compute the number of orbits, ranks and sub degrees of these actions. The results were used to find the number of orbits as proposed by...

Properties of the symmetric groups Sn (n≤7) acting on unordered triples
In this paper, we investigated some properties associated with the action of symmetric group Sn (n≤7) acting on X(3). If Gx is the stabilizer of , the lengths of the orbits of Gx on X are called sub-degrees and the numbers of orbits are called ranks. Ranks and sub-degrees of symmetric groups Sn (n=1, 2, ----) acting on 2-elements subsets from the set X= (1, 2, ---, n)...
