There are 8 points ABCDEFGH
These 8 point form 28 vectors AB AC AD AE AF AG AH BC BD BE BF BG BH CD CE CF CG CH DE DF DG DH EF EG EH FG FH GH.
The direction of these 28 vectors can only be vertically up or vertically down.
I would like the mathematician to create a vector sum or algebraic sum such that: AB+AC+AD+AE...+BC+BD+BE...+FG+FH is always ≥ Zero
