  Semi-Poisson statistics are shown to be obtained by removing every other
number from a random sequence. Retaining every (r+1)th level we obtain a family
of secuences which we call daisy models. Their statistical properties coincide
with those of Bogomolny's nearest-neighbour interaction Coulomb gas if the
inverse temperature coincides with the integer r. In particular the case r=2
reproduces closely the statistics of quasi-optimal solutions of the traveling
salesman problem.
