A permutation is called a TDP permutation if i—a_i(?)j—a_j (mod n), for i≠j. It is easy to prove that a TDP permutation exists iff n is an odd number.C.Tompkins listed the number of TDP permutations for n≤11 in

Since then many people have observed and examined its period changes. Kron found the period was decreasing secularly. Blazhko questioned this secular variation but found a periodic variation in the (O-C) of its time of maximum. Nijland and Detre found the period was very constant. Recently, the results of Szeidl were that the period of XX Cyg has been constant, only展开更多
