Okay, so here is the code. I inserted a couple of print statements so we can see what it does. I am still not sure I understand the logic behind this script. 
#!/usr/bin/perl

use strict;
use warnings;

# To generate the stream of all 1s

sub GenerateStream
{
  my $width = shift;

  my $i;
  my $j;
  my $k;
  my $temp_num = 0;

  my $numofstrobes = 4;
  my @strobes;

  my $all1stream="1" x $width;
  my $x_num = oct("0b" . $all1stream); # to convert string into int

  print "\nx_num=$x_num";

# To Calculate the number of streams

    for($i=4;$i<=$width;$i=$i+4){
           $numofstrobes+=int($width/$i);
     }

 print "\nwidth=$width; numofstrobes=$numofstrobes; i=$i\n";
 #To calculate the bit stream
   
     $j=4;
     for($i=0; $i<$numofstrobes-1; $i++){
         my $k=$j-4;
         my $temp_num=$x_num;
         while($k<$j) {
             $temp_num=$temp_num-(2**$k);
             $k++;
      }
      $strobes[$i]=$temp_num;
         $j+=4;
         $strobes[$numofstrobes-1]=$x_num;
    }
  return @strobes;
}



my @X;
for (my $i = 0; $i < 12; $i++)
{
  @X = GenerateStream($i);
  foreach my $L (@X)
  {
    printf "\n%0.32b", $L;
  }
}
