The sheet table includes the number of strands and type, direction and topology of the sheet. For each pair of secondary structure elements all atomic contacts are listed. Be aware that for a molecule the size of crambin this server already gives you two pages of output. For a 500 residue molecule the output becomes 300 Kbytes. But that gives you a lot of information.
Comments are welcome.
As I understand your question relates to packing of secondary structure elements. There have been several analysis done on helix helix packing. You might like to search medline for references from several groups. Analysis of various packing angles between helices has been done in Chothia group. These are the references that come to my mind rather immediately.
