| The documentation has a note saying: "Base64 has an expansion factor of 6 to 4". I believe it should be 4 to 3. https://docs.python.org/dev/library/base64.html | ||

| Maybe we should just drop that note. To achieve any sort of clarity we'd have to say that base85 is 15 for 12 and base64 is 16 for 12. And putting it that way it doesn't seem like all that much of an advantage :) | ||

| That would also be a solution. Also, the sentence is not quite grammatically correct: "when space [is] expensive". | ||
