    On the Karnaugh mapping chapter in the section larger 4 variable Karnaugh maps I believe there is an error. About halfway down the page it says it maps this equation on a Karnaugh map:

    A'B'C'D'+A'B'CD'+AB'C'D'+ABCD

    which the map is right. But the simplified boolean expression is:

    B'C'D'+A'B'D+ABCD

    Isn't the D in the second product group suppose to be D's compliment D'?
    If not what am I missing?

    Indeed it looks as though you have found an error. The error has also propagated onto the subsequent paragraph. Thanks for pointing it out.
