Active directory group and member properties, DirectorySearcher PropertiesToLoad possible values

Normally you would use code like this, to retrieve values for specific properties of an Active Directory group (specified in string groupName):

   1:  DirectorySearcher search = new DirectorySearcher {Filter = String.Format("(cn={0})", groupName)};

   2:  search.PropertiesToLoad.Add("member"); 

   3:   

   4:  List<string> userNames = new List<string>();

   5:   

   6:  if (result != null)

   7:  {

   8:     for (int counter = 0; counter < result.Properties["member"].Count; counter++)  

   9:     {

  10:        string user = (string)result.Properties["member"][counter];

  11:        userNames.Add(user + Environment.NewLine);

  12:     }

  13:  }

  14:   

  15:  return userNames;

but what are the possible values of properties you can use in PropertiesToLoad.Add()? I couldnt find this information anywhere so I wrote a little snippet to retrieve them, here is the result (29 properties)
