It is well known that every non-cyclic group of order 8 possesses precisely 384 complete mappings (transversals). Here we explain why each of these groups possess the same number of' completeâ€¦ (More)

Spatial patterns of soil properties are linked to patchy vegetation in arid and semi-arid landscapes. The patterns of soil properties are generally assumed to be linked to the ecohydrologicalâ€¦ (More)

We identify a weak critical set in each cyclic latin square of order greater than 5. This provides the first example of an infinite family of weak critical sets. The proof uses several constructionsâ€¦ (More)
