Combinatorics '04 will be the 12th conference of the series organized in Italy, since 1982. This series was preceded by the "International Conference on Combinatorial Geometries and their Applications", in honour of Beniamino Segre, Rome June 7-12, 1981.

These conferences are always held and organized by different Italian Universities.

In the past, Catania Combinatorics organized the following international conferences on combinatorics:

1st Catania Combinatorial Conference (S.Tecla, September 1986)

2nd Catania Combinatorial Conference (S.Tecla, September 1989)

Combinatorics '92 and 3rd Catania Combinatorial Conference (S.Tecla, September 1992)

Catania Combinatorics is pleased of having been charged to organize the conference Combinatorics '04.

The aim of the conference is to present recent developments in Pure and Applied Combinatorics and its connections with Graph Theory, Geometry and Algebra.

Main Topics:

Design Theory, Finite Geometries, Graphs: colorings, decompositions and embeddings.
