“Exponentials on the BBS-ISL Matrix: within 3^n” preview, 2017 
Reginald Brooks
3^2 is on the Prime Diagonal (PD).
All the exponential values above X^2 are on diagonal parallel to PD.
That parallel diagonal is X-steps away from the PD.
The exponential value is also present as an AREA shown in solid color.
