# Problem with citation multiple authors

I need to cite a paper with multiple authors:

@article{DBLP:journals/tit/HammonsKCSS94,
author    = {A. Roger Jr. Hammons  and
P. Vijay Kumar and
A. Robert Calderbank and
Neil J. A. Sloane and
Patrick Sol{\'e}},
title     = {The Z$_{\mbox{4}}$-linearity of Kerdock, Preparata, Goethals,
and related codes},
journal   = {IEEE Transactions on Information Theory},
volume    = {40},
number    = {2},
year      = {1994},
pages     = {301-319},
ee        = {http://dx.doi.org/10.1109/18.312154},
bibsource = {DBLP, http://dblp.uni-trier.de}
}


But when I made the citation it appears as [HKC+94] and I want to be [HKCSS94]. can anyone help me?

Which bibliography style, and which document class, do you use? Separately, do use a citation management package such as natbib? –  Mico Mar 2 '13 at 0:06
I am new using latex, i use report as document class,alpha as bibliography style and i dont use natbib –  Dimitri Mar 2 '13 at 0:08
Thanks. The appearance of the entries in the References section is determined by the bibliography style -- the argument of the command \bibliographystyle. To have a chance to help you, we thus need to know which bibliography style you employ. –  Mico Mar 2 '13 at 0:11
Without switching to biblatex it isn't possible. –  Marco Daniel Mar 2 '13 at 9:09
@Dimitri: I provided an answer. –  Marco Daniel Mar 3 '13 at 9:35

As written in the comments, without using biblatex it isn't possible. By using the package biblatex you have the options minalphanames/maxalphanames. The option maxalphanames requires a number and it represents the number of authors which will be counted for the label of the style alphabetic. In your case it should be 5.

Here a MWE with the correct compilation order using arara

% arara: pdflatex
% arara: biber
% arara: pdflatex

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[style=alphabetic,maxnames=99,maxalphanames=5]{biblatex}

Did you compile with pdflatex+biber+pdflatex? Do you get any errors? –  Marco Daniel Mar 3 '13 at 18:40
