+  If you intend to change any of these values, you must also recompute
+  the corresponding solutions below.  Basically, these are just hex
+  strings (for the big integers) or integer values (for the digits).
+
+  The comparison tests think they know what relationships hold between
+  these values.  If you change that, you may have to adjust the code
+  for the comparison tests accordingly.  Most of the other tests
+  should be fine as long as you re-compute the solutions, though.
