The problem is the following: I want to export a list of equations I have set up with Mathematica such that I am able to import it back to Mathematica and continue to work with it, i.e. as if I had just set the equations up and never exported/imported them. The equations are of the following form:
F[0,1,1,2][1,1]^3+F[0,0,0,1][2,3]*F[2,2,2,1]^2==F[3,4,1,1][0,0]*F[0,1,0,1][2,2]*F[1,1,2,3][3,2]
Here, the $F[0,1,1,2][1,1]$ etc. are the variables; this does not refer to any other list or something, it is just a naming scheme. Now I have a list of approximately 60.000 of these equations. I have tried several options of the Export/Import-function in Mathematica, but I always encounter the following problem:
After importing the equations again, Mathematica does not recognize the $F[0,1,1,2][1,1]$ as variables anymore, especially I am not able to let a replace pattern like $/.F[0,1,1,2][1,1]\rightarrow1$ act on the list.
Does anyone of you have a suggestion how to export/import a list of equations like this?
