Notes:
It is shown that for structures in which the coordinates of atoms have been randomly generated, the probability formula gives an underestimate of the experimental probability of the Σ2 relation. Concentration of atoms in planes increases the number of reliable triplet sign relations. Although the presence of a non-crystallographic centre of symmetry results in a larger number of triplet relations with high EHEKEH - K values, the percentage of failures is increased compared with random structures.
