چکیده
An [18, 9, 8] extremal self-dual code over GF( 4 ) and related [17, 4, 12], [17, 8, 8],[17, 9, 7], [17, 13, 4] codes are investigated. Simple coordinates are given for these codes,and their minimal weight codewords and automorphism groups are determined. Thegroups are all isomorphic to 3 × (PSL 2 ( 16 ). 4 ). __________* This appeared in ‘‘Discrete Math.’’, vol. 83 (1990), pp. 205–212.** Supported in part by a grant from the Louisiana Educational Quality Support Fund.Present address: AT&T; Bell Laboratories, Holmdel, NJ 07733.

THE AUTOMORPHISM GROUP OF AN [l&9,8] QUATERNARY CODE
An [18,9,8] code Ce18 over GF(4) was constructed in [6] as an extended cyclic code, and Pless [9] describes the same code as an extended “Q-code”. This code is of particular interest since it is an extremal quaternary code: an [n, n/2, d] self-dual code with d = 2[n/6] + 2 ([6, p. 2951, [3, p. 2051). In the present note we give new coordinates for this code, enabling us to find a simple descrip...
متن کاملProjections of Binary Linear Codes onto Larger Fields
We study certain projections of binary linear codes onto larger fields. These projections include the well-known projection of the extended Golay [24, 12, 8] code onto the Hexacode over GF(4) and the projection of the Reed-Muller code R(2, 5) onto the unique self-dual [8, 4, 4] code over GF(4). We give a characterization of these projections, and we construct several binary linear codes which h...
متن کاملOn the classification of the extremal self-dual codes over small fields with 2-transitive automorphism groups
There are seven binary extremal self-dual doubly-even codes which are known to have a 2-transitive automorphism group. Using representation theoretical methods we show that there are no other such codes, except possibly n = 1 024. We also classify all extremal ternary self-dual and quaternary Hermitian self-dual codes.
متن کاملNILPOTENCY AND SOLUBILITY OF GROUPS RELATIVE TO AN AUTOMORPHISM
In this paper we introduce the concept of α-commutator which its definition is based on generalized conjugate classes. With this notion, α-nilpotent groups, α-solvable groups, nilpotency and solvability of groups related to the automorphism are defined. N(G) and S(G) are the set of all nilpotency classes and the set of all solvability classes for the group G with respect to different automorphi...

The concept of quaternary prevention (P4) refers to the idea that medicine has acquired the ability to damage through the proper exercise. Family medicine or general practice has the duty of recovering the ethical values and the exercise of a profession with the doctor-patient relationship serving to people’s humanity. In the fourth Congress of Family and Community Medicine, held in Montevideo ...
