When you say, "... three possibilities" what are you referencing? The only thing that stands out to me is the order of reset, load, and inc columns; if that's the case, how would that change the canonical expression? There would still be 6 terms with exactly the same values per term (just rearranged values.)

I keep hearing about Karnaugh maps; I suppose I should investigate.

In the meantime, I'll work on reducing my sel[1] expression, with the goal of getting to the 2 input OR gate.

Really appreciate your time. Thanks.
