When one looks the total of solutions, you might get mind that it is HOTF-problem, but that is not the case. This problem would be a lot higher without these forms (A-D). Here A and C are similar in content, and B and D as well. This would have been a prizewinner without these forms which make the problem quite complex. Still like the problem, but the idea needs better construction.
