En = Fn(B, C) + ???Fn(D)???

[NotLKH]

Useing the information as presented in the attached Image,
Can you finish the Identities for En such that in the 9 Row Equations
En Em, Either:

1) All the D Elements sum to Zero

or

2) You result in the Identity D₁ + D₃ + D₅ = D₂ + D₄ + D₆

???

{ the "Such That" info displays what the current E equations sum to, useing the "current" values of En. }
