I read from a textbook that there are two boundaries conditions that may be used in order to determine the energies of N electron system in a cube of volume V (and side a).
...

...
As you can see in the attached file, the energies got by using the the two boundary condition methods are different.
The textbook however states that these energies are not different but are EQUAL if proper values of n1, n2, n3 are taken. How can that be possible? I just see two different things that cannot be equal here. Please help.
Notice that ni = 1, 2 ,3 , ... in the first boundary condition and
ni = ... -2, -1, -1,0 , 1, 2 ,3 , ... in the second condition.
(i = 1,2,3)
