Parameters

Apart from the condition that they must not vanish to give a non-trivial solution and a non-singular solution with non-vanishing denominators, the following parameters are free:
 q28, p12, p5

Inequalities

In the following not identically vanishing expressions are shown. Any auxiliary variables g00?? are used to express that at least one of their coefficients must not vanish, e.g. g0019*p4 + g0020*p3 means that either p4 or p3 or both are non-vanishing.
 
{q28,

 p5,

 g0021*q28 - 3*g0031*q28 - 3*g0059*p12 - 3*g0066*p5,

 g0127*p12 + g0134*p5}


Relevance for the application:



The equation: 


       4
f =(Df) *f*p5 + f  *f *f*p12
 t               2x  x
The symmetry:
                          1      2
f =Df *Df*f  *f *f*q28 - ---*(Df) *f  *f *f*q28
 s   x     2x  x          3         3x  x
And now in machine readable form:

The system:

df(f(1),t)=d(1,f(1))**4*f(1)*p5 + df(f(1),x,2)*df(f(1),x)*f(1)*p12$
The symmetry:
df(f(1),s)=d(1,df(f(1),x))*d(1,f(1))*df(f(1),x,2)*df(f(1),x)*f(1)*q28 - 1/3*d(1,
f(1))**2*df(f(1),x,3)*df(f(1),x)*f(1)*q28$
