Thanks for your message.

Different results can be produced at different precisions,
basically because two numbers which are the same at low precision are
different at a higher precision.

So I don't think these three tests show that the software is incorrect,
but they show I need to do more work in defining the tests and
particularly the starting set given by ssfn. It excludes 2 from the set,
which was a mistake.
