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:
 q11, p5, p2

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.

The equation: 


                 2          2
b =Db *Db*p5 + b  *p5 + b *b *p2
 t   x          x        x
The symmetry:
              2                           2         3   2
b =(2*Db *Db*b *p2*p5*q11 + 2*Db *Db*b *p5 *q11 + b  *p5 *q11

And now in machine readable form:

The system:

df(b(1),t)=d(1,df(b(1),x))*d(1,b(1))*p5 + df(b(1),x)**2*p5 + df(b(1),x)*b(1)**2*
p2$
The symmetry:
df(b(1),s)=(2*d(1,df(b(1),x))*d(1,b(1))*b(1)**2*p2*p5*q11 + 2*d(1,df(b(1),x))*d(
