To finish some of my research, I'd like to use sympy to compute a 
multivariate nonlinear system of equations. This system is under-determined 
but I can guarantee it is solvable. 

The simplest case I would like to solve has 21 unknowns and 12 constraint 
equations; see following for all constraint equations. Ideally, I would 
like to have a solution set for the 21 unknowns (I'll call them "a" - "u") 
that has a small norm2. 

1 = a*j*p + d*l*q + g*n*r
0 = b*j*p + e*l*q + h*n*r
0 = c*j*p + f*l*q + i*n*r
0 = a*k*p + d*m*q + g*o*r
1 = b*k*p + e*m*q + h*o*r
0 = c*k*p + f*m*q + i*o*r
0 = a*j*s + d*l*t + g*n*u
1 = b*j*s + e*l*t + h*n*u
0 = c*j*s + f*l*t + i*n*u
0 = a*k*s + d*m*t + g*o*u
0 = b*k*s + e*m*t + h*o*u
1 = c*k*s + f*m*t + i*o*u

Currently, I am trying to use sympy's "solve" for all of these equations 
and it hasn't even completed computation in 24 hours.

Is my problem simply too complicated or am I using the wrong function for 
this? I appreciate any suggestions you may have.

Thanks for your time!
