Luhmann just intuitively came up with the same addressing concept as represented by a Xanadu Tumbler, essentially it relies on (implicitly) transfinite numbers:
Only, he realized that using letters for every other number makes the dot number dot sequence as a separating character redundant, thereby shortening the address length tremendously, and he didn't need versioning in the way the Xanadu devs thought it would need.
