    It must also be related to the slavic grammar of Subject Object Verb. Reversed this is not the same as Operator Source Destination but Operator Destination Source. Reverse the last two and you get RPN, which reverses the subject/object from the reverse of the polish grammar.

    I have always been a bit confused about these sequences in computer and human languages, but the intuitive grasp of the process of structuring we learn as we learn to speak, so anyone can understand it, if they try. It's an issue of serialisation.

    In mathematical notation you are not limited to a sentence like in english, the relations between parts of an expression are more graphically displayed. x = y/z, assumes that division the quotient comes first. The Object in this sequence is the divisor, because it acts on the quotient. But in mathematical notation the quotient is at the top and the divisor is at the bottom, and the variable is on the left.

    I presume this Lukasiewicz was devising schemes for programming calculators, since an operator must input the parts of the operation in some arbitrary order (at minimum out of 6 sequences) into the memory to enable the operation.

    Again, thanks for the clarification. I get a kick out of the word-detective puzzle game of understanding something that I only know some part of. My mother is a huge fan of detective stories, I love to do detective work on information, always testing myself to see how much I can derive instead of memorise. Derivations are much faster to absorb, because they are less complex (resequencing, rather than storing new data plus sequence information).
