thnxs a lot for sense now but to be very frank as you related the formula with N2 = (N-1) * 4 + (N-2) * (N-2) that,s i do not know but how this formula N2 = (N-1) * 4 + (N-2) * (N-2) came into existence I know I have proved two formulas for cube or square through points on pyramid .ok it,s happened all of a sudden when i was working on straight line divided into same ratio got another line again divided into same ration till i got the one point then the miracle happened and got amazing results.
For kind information i never manipulate formulas .... for every formula i have the basic concept from wher and how this formula i got. ok.
thnxs for quoting and keep continue
I have proved and have proof of this formula which you mentioned and two more too. o.k dear.
