The Nonexistence of a Distance-Regular Graph with Intersection Array {22, 16, 5;1, 2, 20}
We prove that a distance-regular graph with intersection array {22, 16, 5; 1, 2, 20} does not exist. To prove this, we assume that such a graph exists and derive some combinatorial properties of its local graph. Then we construct a partial linear space from the local graph to display the contradiction.

We prove that a distance-regular graph with intersection array (5, 4, 3, 3; 1, 1, 1, 2) does not exist. The proof is purely combinatorial and computer-free.

Since its inception over 35 years ago, Rietveld refinement (Rietveld, 1969) has come a long way. In the beginning, the aim was to carry out crystal-structure refinement using neutron diffraction. As its primary purpose was refinement of the perfect crystal structures of polycrystalline samples, there was a need to introduce corrections to peak intensities and positions, as calculated for a perf...
