I have some tensor contractions, e.g., A[abcd] B[cdef] = C[abef], where A[abcd] = A[badc] and B[cdef] = B[dcfe]. I did not find information about symmetry in einsum in NumPy. Is there any Julia package can handle tensor contractions with symmetries (possibly calculations will be faster)?

I found Introduction · TensorKit.jl

mentions some symmetries and examples in Tutorial · TensorKit.jl

Is the performance comparable with einsum/opt-einsum in NumPy?
