Your code does not run and has a lot of errors, anyway,
if I understand your code correctly, here's something that will
work for you.
use Data::Dumper;
# note that you do not need to explicitly fill in the
# elements of the array one by one, make use of
# perl's lists.
my @lite = (
[qw/2 5 0 999 999 0/],
[qw/4 3 0 999 999/],
[qw/1 4 0 999 999/],
[qw/1 4 0 999 999/],
[qw/4 1 0 999 999/]
);
my %h;
foreach (@lite) {
# construct a key made of the X value x the Y
# value and count on that being uniq.
my $xy = $_->[0] . 'x' . $_->[1];
# hash keys are uniq,
# so we make the value an array reference
# containing the original x and y values.
$h{$xy} = [$_->[0], $_->[1]];
}
# just retrieve the values from the hash.
my @filtered = values %h;
print Dumper(\@filtered);
He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
