I think you must be misremembering; if you dial a sequence of 153 digits, you can't possibly test more than 149 different 5-digit substrings.

- Zanni 8y agoPossibly. It was 20 years ago. I'm reconstructing via my (possibly flawed) understanding of the linked article. (My vague recollection was something like 250 digits for a 4-digit passcode.) And I just realized I mistakenly conflated 5-digit permutations of 5 digits with 5-digit passcodes of 10 digits. Whoops.
