Question: American Express Business Travel uses a six letter record locator number

(a) How many different RLNs can be created using capital letters (A­Z)?
(b) What if they allow any mixture of capital letters (A­Z) and digits (0­9)?
(c) What if they allow capital letters and digits but exclude the digits 0 and 1 and the letters O and I because they look too much alike?
