In the plurality of methods of assembling, the chaining is of an overwhelming importance since, being the most efficient way of not doubling useless
the surfaces, through superposition, they are constituted in volumes, in perpetual expansion, in any spatial direction.
There have coupled, three nfc with three nfc enantiomorphe and resulted a closed spatial complex (like in the fig. 7.9), under an annular shape,
a "Matrix Cube" (fig. 7.15).
This nfc is coupled through chaining with another nfc (fig. 7.16)
It results a balanced ensemble, stable in vertical if it is leaned upon the ground with the two extreme sides (fig. 7.17).
One can remark (observe) that, to these structures of the Matrix Cube, the "vacuum" can have a very important role for the construction.
