Superscript

Sponsorship the way you would do it
A superscript is a number, figure or indicator, that appears above the normal line of type, when used in a formula, mathematical expression or description of a chemical compound, and to indicate the presence of a footnote in a document. Probably the most famous superscript is the number 2 in Einstein's theory of relativity, E=MC2.
