Here's the explanation to the pattern: five items won't fit into one row of
four columns, but when you divide it into two rows, you don't need four
columns to populate it.

What layout do you want in that situation?

1  3  4  5
2  NOTHING NOTHING NOTHING

or

1  3  5
2  NOTHING  NOTHING

are possibilities.

The solution I submitted uses a variable for the number of columns. You can
recompute the variable after the number of rows has been computed as
follows:

my $nRows = int(($n+$nCols-1)/$nCols);
$nCols = int(($n+$nRows-1)/$nRows);

That changes the behavior to the second of the two possibilities that I
suggested earlier.

I went ahead and made that change. I also changed the behavior so the test
script tries values of 1 through 20 if no query string is specified.

Try http://www.exelana.com/cgi-bin/test.cgi and see if that is close to what
you want.
