| Abstract: | The prime order cyclic graph was studied by Group theory and Number theory, and the constuction of normal subgroup of cyclic group was discussed. The general method for looking for the lower bounds of Ramsey numbers R n (5) and some new lower bounds of Ramsey numbers R n (5) were given. |
