Thanks Rolf,
I could'ent make it work at first. But after a minor modification (calling it TensorFunction2 instead of TensorFunction) it almost worked according to the intention.

TensorFunction2[R_, i__] :=
 Signature[{i}]*TensorFunction[R, Sequence @@ Sort[{i}]] /; !

but this kills canonical order of TensorFunction2[R,a,b,c,d] while the other symmetries work just fine.

However by removing the condition "/; !OrderedQ[{i}]" fixes the last mentioned problem! Im not sure if this will create other unknown problems (by removing that condition).

Much appreciated!
