Problem

What is the maximum auto generated id in Google App Engine datastore? Why this question? I would like to show a more user-friendy id to my customer in a format like ####-####-#### using the alphabet: ``` 0123456789ABCDEFGHIJKLMNPQRSTUVWXYZ ``` the character O has been removed to avoid confusion with the digit 0. I need to know how many groups of ### are needed to represent all the ids.
