Anything that WM alone claims needs more proof that just his word to convince anyone sensible.

Until one has an unambiguous rule determining the terms of a sequence, which does not exist in WM's "sequence", there cannot be an unambiguous limit. > > > > > > > > > > No; it has no limit. > > > > > It has an improper limit in analysis, namely oo. It has a limit in set > > > theory.
Until WM can show that his sequence of numbers is well defined, it has no limit as a sequence of numbers, and until WM can show that his sequence of numbers is really a sequence of sets, which he has not done, it certainly cannot have a set limit.
And, quite probably, even if WM finally does show both of those things, it may be that neither limit will be defined by any standard limit process, either as a number sequence or a set sequence. > > > > Unless it is redefined as a sequence of sets, which it is not in its > > original form, set theory says nothing about any limit for it. > > Sets of numbers are sets, whether or not they appear in my sequence of > real numbers. There is no redifinition necessary.
The only set of numbers involved would be the set of all numbers in the sequence and that is not a sequence of sets. > > > > Please do not mistake analysis and set theory.

To the best of my ability to see, there is no pattern of terms so obvious as to rule out all other possibilities once the present pattern extends far enough to needs a successor to digit 9.
Perhaps WM will have pity on my weak vision and explain his rule for that sequnce less ambiguously. --
