Unknowns
All solutions for the following 13 unknowns have to be determined:
p1,p2,q1,q2,q3,q4,q5,q6,q7,q8,q9,q10,q11
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.
