                         It is inexpensive and needs only one GPU week of training. Our retriever leverages LeanDojo's program analysis 
                         capability to identify accessible premises and hard negative examples, which makes retrieval much more effective. 
                         Furthermore, we construct a new benchmark consisting of 98,641 theorems and proofs extracted from Lean's math library.
