My computer has calculated at least 100 hours with 4 threads and several programs (written in 64 bit assembly), but all I receive is something like
6 9 6 9 12 9 6 15 6 15 3 12 6 9 12 9 6 9 15 3 12 6 15 6 ,
the numbers being 216 times the probability of the 24 triplets {x,y,z};
and we want 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9.


I use linear combinations of a,b,c, “and” and “or”.
The update(1/11) contains the term “b&1234”as an example. For me, that is a little bit misleading: only numbers <=7 make sense after “b&” (0<=b<=6; b has only 3 bits).

There is one more evening to tinker with this one. Unlocking date is listed as 12/02.

I had no time all month, but maybe tonight... being Friday and all.
