Let's assume that [0,1] is completely covered by R members.
-------------------
So here the draft of my idea:
[0,1] is a non-empty closed interval that includes all the real numbers between 0 and 1 (including 0 and 1).
Let X be the set of closed intervals of R members that are included in [0,1], as follows:
X={[0,x1],[x1,x2],[x2,x3],[x3,x4],[x4,x5],…}, where |X|=|X={[0,x1],[x1,x2],[x2,x3],[x3,x4],[x4,x5],…}|
Each member of set X includes |R| amount of (almost only) unique R members along [0,1] (it is “almost only unique ...” because one or two R members in any given X member, overlapping one or two R members in one or two some other X member(s)).
If X has a finite cardinality, then there is no problem to completely cover [0,1] for example:
X={[0,1]}
X={[0,x1],[x1,1]}={[x1,1],[0,x1]} (the order of the members is insignificant, whether |X| is some finite cardinality, or even if |X|=|N| (in case that X is an infinite set)).
X={[0,x1],[x1,x2],[x2,x3],...,[xn,1]} etc. … (again, the order of the members is insignificant, whether |X| is some finite cardinality, or even if |X|=|N| (in case that X is an infinite set)).
But what if |X|=|N|?
In that case the closed interval of the form [x|N|,1] can’t be in the range of set X (|N| can’t be used as an index within set X, because |X|=|N|) and we can conclude that X={[0,x1],[x1,x2],[x2,x3],[x3,x4],[x4,x5],…}, where no X member can reach number 1 of the interval [0,1].
The closed interval of the form [x|N|,1] is equivalent to the mathematical expression |N|<|R|.
