Sudhansu Chokroverty,Michel BilliardWe fully update the existence problem of orthogonal designs in order 16..It is interesting to note that all n variable designs in order 16 for n=1,2,…,5 and all 6 and 7 variable designs which exist can be constructed from known 8 and 9 variable designs.

Some incidence structures of maximal rank,Generic algebra methods are used to translate combinatorial results about Weyl groups into statements about classical groups. A consequence is the maximal nature of the rank of the incidence matrix of isotropice-subspaces vs isotropic f-subspaces of a finite vector space V with a form F, in many cases.
