Labels of points in a numeric list converted to letters

[valdel (Valdelírio da Silva e Silva)]

Thank you for the efforts each of you put into solving my problem. This forum is extremely helpful. Through a series of ideas, I managed to solve the problem using only the Desmos calculator. Here is a calculator for converting from decimal base to any other base, in which I used letter labels from base 11 to base 36. (Unfortunately, I don’t know who came up with the original idea for the calculator, and I only added points, lists, and text for my own purposes.)
