*permutation code*of length

*n*and distance

*d*is a set Γ of permutations from some fixed set of

*n*symbols such that the Hamming distance between each distinct

*x*,

*y*∈Γ is at least

*d*. In this note, we determine some new results on the maximum size of a permutation code with distance equal to 4, the smallest interesting value. The upper bound is improved for almost all

^{2}). For the pure Manev potential γ = 0 we discuss both the continuous case and the

*N*-body problem and show that global solutions will not exist if the initial energy is negative. Certain global solutions can be constructed from local ones by a transformation which is peculiar...
