Well, not quite—the mapping from the disjoint cycles to the ground settin...

Moreover, some of the reports are even c...

متن کاملA Turing Enigma
I describe my investigations into the highly-secret role that Alan Turing played during World War II, after his pre-war theoretical work on computability and the concept of a universal machine, in the development of the world’s first electronic computers. These investigations resulted in my obtaining and publishing, in 1972, some limited information about Turing’s contributions to the work on c...
