Abstract
Aims. A statistical method is applied to galaxy samples to search for possible repetitions on 100 Mpc scales.
Methods. The method is based on autocorrelations, and is constructed in such a way that it does not detect structures of changing scales.
Results. The signal for non-randomness is moderate but significant. This result argues for homogeneity well above 300 Mpc scales.
Key words: large-scale structure of Universe -- distance scale -- cosmological parameters

| What is OpenURL? |
The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
