Dear Alexey,
I should probably go back and re-read the lecture on J & H. So the third personality according to Nabokov would be J minus H?
My theory of PF indeed is S = K = G, and what underlies that is S = C, K = C and G = C minus (C−).
Intriguing. Could this be the P. . . F proof?

p.s. It may not be a fire-proof proof - - let's see who casts the first shot.
