Unknowns

All solutions for the following 61 unknowns have to be determined:
a1, ..., a19, b1, ..., b42 

Inequalities

Each of the following lists represents one inequality which states that not all unknowns in this list may vanish. These inequalities filter out solutions which are trivial for the application.
