Symmetry
• Symmetry is a reserved word in xTensor`. It is the head of symmetry expressions.
• An example of a symmety expression for a tensor Rie with the symmetries of a Riemann tensor is
Symmetry[4,,{●1→G,●2→F,●3→D,●4→K},StrongGenSet[{1,2,3},GenSet[Cycles[{1,3},{2,4}],-Cycles[{1,2}],-Cycles[{3,4}]]]]
