    Standard symbol for exclusive disjunction?

    Hello All:

    Is there any "universally agreed-upon" symbol to represent this exclusive disjunction:

    p v q & ~(p & q) ?

    That is, would there be one symbol that one could use such that "p * q" would be equivalent to the above statement?

    Thank you very much.

    The plus symbol inside a circle.

    Also, in letters:

    xor

    Universal? No. But a common one I've seen is disjunction with a bar underneath, \underline{\lor}. Wikipedia lists the circle plus, \oplus, as another popular choice.

    Not to be too flippant, but that are no universally agreed-upon symbols period.
    However, one very often sees the exclusive or symbolized as
    p\underline \vee  q
    That means exactly one of p or q is true.
