# Indices Notation

343
Is there an equivalent notation to Capital Pi notation (multiplier) and Sigma notation (summer) for raising to the power?

e.g. x1^x2^x3^x4...^xn=Notation(i=1 to i=n)(xi)

Where "Notation" represents the symbol in question (analogous to Sigma for sums, Capital Pi for multiplication)?

You mean something like:
$$\Xi_{i=1}^n x_i = x_1^{x_2^{x_3^{\cdots x_n}}}$$ ... no.
