Abstract

A new series of ℤ₄-linear codes of high minimum Lee distance is given. It is derived from the ℤ₄-linear
representation of the Kerdock codes. The Gray image of the
smallest of these codes is a nonlinear binary (114, 2⁸, 56)-code, and in the second smallest case the Gray image is a nonlinear binary (1988, 2¹², 992)-code. Both codes have at least twice as many codewords as any linear binary code of equal length and minimum distance.
