We assume that:

Second-rank Einstein tensors can be expressed as B-matrix strings which are a product of statistical theory called Cairo techniques.

The 4x4 transition matrix B equivalent to Einstein's relativity tensor is expressed as follows:

a11 a12 a13 a14

a21 a22 a23 a24

a31 a32 a33 a34

a41 a42 a43 a44

The 16 variables a,s above are subject to the 4 conditions defining the transition matrix chains B, namely,

a12=a21

a13=a31

a14=a41

a23=a32

a24=a42

a34=a43

a11=a22=a33=a44=const.

The 10 constraints above reduce the number of Einstein tensor variables from 16 to 6.

As simple as that.
