I need to evaluate the tensor product 10 times in a given list( {g,e,r})

Here I have evaluated for 3 times...


Evaluated for 6 times...

#\[TensorProduct]#\[TensorProduct]#\[TensorProduct]#\[TensorProduct]#\[TensorProduct]#&[{g,e,r}] (*n=6*)

Each time I need to include the tensor product on the list. Is there any better way to do this for large no.?

You can generate the chained function on-the-fly for each n:

chainTensorProduct[list_, n_Integer] := Function[TensorProduct @@ ConstantArray[#, n]]@list


#\[TensorProduct]#\[TensorProduct]#&[{g, e, r}] == chainTensorProduct[{g, e, r}, 3]
(* True *)
