How is the Layout of an "Eighteen Point" AF System??

Here is an IQ Question! How to make an "18 Point" new AF system with symmetry? What is the possible layout??If anyone can make it, please let us know! Otherwise, the previous rumour is fake, at least for the design and features of the specs on the AF part that were told (being have the "Portrait" and "Night" AF-*C* modes is just a JOKE!). In fact, it is just impossible to draft such a layout,
