+# ProofNet#
+
+ProofNet# is a Lean 4 port of the [ProofNet](https://huggingface.co/datasets/hoskinson-center/proofnet) benchmark including fixes.
+This benchmark has been made compatible for all Lean versions between v4.7.0 and v4.16.0.
+
+A comparison with some of the other existing ports can be found at:

+
+### Original Dataset Summary
+
+ProofNet is a benchmark for autoformalization and formal proving of undergraduate-level mathematics. The ProofNet benchmarks consists of 371 examples, each consisting of a formal theorem statement in Lean 3, a natural language theorem statement, and a natural language proof. The problems are primarily drawn from popular undergraduate pure mathematics textbooks and cover topics such as real and complex analysis, linear algebra, abstract algebra, and topology. We intend for ProofNet to be a challenging benchmark that will drive progress in autoformalization and automatic theorem proving.
