A lattice in geometry is an infinite surface, that divides space in 2 infinite parts. The surface is formed by connecting infinite units of some finite surface.
A drawing from the P surface, a triply periodic surface, can be found on the following link: http://www.susqu.edu/brakke/evolver/examples/periodic/periodic.html
The build with magnets is an approximation of Schwarz' H surface, the 13th surface shown in the linked article.

![Different polarity systems in 5x5- and 6x6-squares, magnets tutorial
This video shows that 5x5- and 6x6-squares can be made with different polarity systems. It is a video response to Dimitri Tishchenkos video [Tutorial] Squares where he attempts to make different 4x4-squares. With the string method I use to prove that two squares have a different polarity system, all possible constructions of a 4x4-square behave the same. This does not prove that they all have the same polarity system, but probably they do. Yet 5x5- and 6x6-squares CAN have different polarity systems as shown in my video.
