AUTOMORPHISM GROUPS OF THE EXTENDED QUADRATIC RESIDUE CODES OVER Z_(16) and Z_(32)

摘要

Let ) deZn_(1o6te the integers modulo 16. Z_(16)is a ring which has 2, 4, 6, 8, 10,12,14 as zero divisors. A set of n-tuples over )) is called a code over Z_ (1o6r a code if it is a Z_(16)-module. Similarly one can define a -coZ(d32) e.
