I'm afraid I have to dissappoint you.

If you had actually proven Sigma(27)>f_w^2(12), yes that would be a great bound. The current best is approximately f_(w+2)^2(13).

However, your machine uses 6 colors (1,_,w,W,i,|.) So you have proven Sigma(27,6)>f_w^2(12) which is crushed by my Sigma(19,5) > f_e0(10^352).
