Abstract :
The classical Elias bound for the Lee metric is weak when the size of the alphabet is larger than the minimum distance. A modified upper bound which is also strong for large alphabets is derived. This bound then is used to prove a nonexistence theorem for perfect Lee codes over large alphabets.
