Description
これは数学的には等価であるが、計算という観点から違いが出てくる。計算と証明を同時に行う Lean だからこそ出てくる定義についての疑問であって、これに答えることは Lean らしさとは何かを理解することに繋がる。

Research direction
The issue names Fin n → A and Vector A n but no files, tests, or entry points. Start by locating the examples or documentation that define these types, then compare their computational behavior in Lean. Done means a clear explanation of their mathematical equivalence and why their definitions differ for computation and proofs.
