I already found that there is one case when left part of double inequality not performed. It is folowed that PC exists. Nevertheless thank you.

Hi! How are the searches going? In the project statistics, the progress so far seems to be unresultative... My own brutal force application still brought nothing too. May be this can be useful to you:

Re: [sub-project] Perfect cuboid
One of the face diagonals is divisible by 4, and I had every right to write: (defg)^2=16n^2. Is it clear?
Let's transform both last equations to the reduced form and try to determine the integer roots: Are you still in doubt?

Hi! Let me invite you to this discussion:

I think there is not roots among the divisors of the free member of two last equations.

Are you looking for complex values of the face diagonal? It is obvious that if integer values are needed, not complex values, when x^2<4e^4f^4. Insert this condition and try the same one more time, please.

The discriminant cannot be zero, I made a mistake above, there will always be two roots.
Maybe you will be interested to solve the last expression in integers, it will be the geometric mean, then both roots will be integers, if I don't mistake:
