Compact encodings of the web graph are required in order to keep the graph on the main memory and to perform operations on the graph efficiently. In this paper, we propose a new compact encoding of the web graph. It is 10% more compact than Link2 used in the Connectivity Server of Altavista and 20% more compact than the encoding proposed by Guillaume et al. in 2002 and is comparable to it in terms of extraction time.
