Centrosymmetric and pseudo-centrosymmetric structures refined as non-centrosymmetric.

The behaviour of the Flack parameter for centrosymmetric and pseudo-centrosymmetric crystal structures based on crystal structures published as being non-centrosymmetric is presented. It is confirmed for centrosymmetric structures that the value obtained for the Flack parameter is critically dependent on the Friedel coverage of the intensity data, approaching 0.5 for a coverage of 100% and stic...

Restricted centrosymmetric permutations

We characterize the sets of centrosymmetric permutations, namely, permutations σ ∈ Sn such that σ(i)+σ(n+1−i) = n+1, that avoid any given family of patterns of length 3. We exhibit bijections between some sets of restricted centrosymmetric permutations and sets of classical combinatorial objects, such as Dyck prefixes and subsets of [n] containing no consecutive integers.
