%N A106730 Product-based sequence of a Markov type based on a functional addition 
               group.
%C A106730 The object of this sequence is to show a product Markov can be formed 
               from an Addition group based on the primes. Modulo five can be taken 
               as a signed modulo three: {0,1,2,3,4}->{-2,-1,0,-1,-2}
