The values on the diagonals of the original tensor remain positive.
The influence is schematically given in fig. 3.
In the abridged tensor ABCD becomes A'B'CD and EFGH
becomes E'F'GHCD, GH, and F'G which do not change position,
are dotted for reasons to be mentioned later.
If the following rules are observed the rows of the original tensor
can be easily written out. The abridged tensor of the net in fig. 2
is shown in (11):

One enters the figure, multiplying the given factors by 1 or
1 (indicated by the sign between the brackets). At the crossing
