S&M (with Honour)

In the figure below, there are 3 pairs of capital sigma (Σ) plus Z numbered 1 to 3. In each pair of Greek letters, the two letters face each other on a line between a number n and it's complement n' (n prime).

We note that of the 6 × 3 [18 (9 × 2)] lines in the figure, 3 are left uncoloured. So, in addition to the Brick's №s, there is a real presence of the Tesla №s.
