On the Number of Distributive Lattices
We investigate the numbers dk of all (isomorphism classes of) distributive lattices with k elements, or, equivalently, of (unlabeled) posets with k antichains. Closely related and...

Isomorphism Classes of Picard Curves over Finite Fields
In this paper we determine the number of isomorphism classes of Picard curves, i.e., superelliptic curves y3 = f(x) of genus three, over finite fields of characteristic different f...

A Census of Small Latin Hypercubes
We count all latin cubes of order n 6 and latin hypercubes of order n 5 and dimension d 5. We classify these (hyper)cubes into isotopy classes and paratopy classes (main classe...

The exceptional hyperplanes of DH(5, 4)
In [2], we showed the existence of five isomorphism classes of hyperplanes in each dual polar space of type DH(5, q2). We also proved there that every hyperplane of DH(5, q2) bel...
