There is also a strong five exponentials conjecture formulated by Michel Waldschmidt.Waldschmidt, (1988). It would imply both the strong six exponentials theorem and the sharp five exponentials conjecture. This conjecture claims that if x1, x2 and y1, y2 are two pairs of complex numbers, with each pair being linearly independent over the algebraic numbers, then at least one of the following five numbers is not in L∗:
