%E A060953 Lambert Klasen (Lambert.Klasen(AT)gmx.net), Mar 31 2005, kindly rechecked this sequence against the Mishima web site and found no errors.
%E A060953 Corrected Apr 10 2005 at the suggestion of _James R. Buddenhagen_. There were errors caused by the fact that Mishima lists each curve of rank two twice, once for each generator.
