“…On the determination of the protein amino acid system (as constituents of the genetic code), also with the golden mean and the Fibonacci series, see in: (Rakočević, 1998b;2011bRumer, 1966) 4 ; in Gray code model of GC (Swanson, 1984) and GC binary tree (Rakočević, 1998b)]. In the argumentation of the working hypothesis, we consider that the coexistence of GC with Boolean spaces (Swanson, 1984;Rakočević, 1994Rakočević, , 1997bRakočević, , 1998b 5 , analogy with quantum physics (Shcherbak, 1994(Shcherbak, , 2008, 6 analogy of genetic and chemical code (Rakočević, 2018b) and the existence of "arithmetic inside the universal genetic code" (Shcherbak, 2003) are established facts.…”
