There are four possibilities: (1) n points on an irreducible conic; (2) n=n1+n2 points with n1 >= n2 >= 2, where n1 points are on one line, n2 on another and none are where the two lines meet; (3) n=n1+n2+1 points with n1 >= n2 >= 2, where n1 points are on one line, n2 on another and one point where the two lines meet; and (4) n+1 points with n > 1 on a line and one point off the line.

Please do not use inputs greater than 10000. If you do, the inputs will be changed to values of -1, which the scripts will then change to appropriate default values.
