What are the differences between the Yogacarin & Brahma Net Sutra Boddhisatva Precepts?

This google books link indicates that there is a version of the Bodhisattva Precepts with 4 major and 43 minor (as compared to 10 major and 48 minor in the BNS Bodhisattva Precepts). Does anyone know what these are? I will also provide a link to google to demonstrate that google does not provide an answer since that seems to be a common answer here.
