EXTENSIONS
| Lambert Klasen (Lambert.Klasen(AT)gmx.net), Mar 31 2005, kindly rechecked this sequence against the Mishima web site and found no errors.
Corrected Apr 10 2005 at the suggestion of James Buddenhagen (jbuddenh(AT)gmail.com). There were errors caused by the fact that Mishima lists each curve of rank two twice, once for each generator.
