If those sets of lines are all well-ordered sets of lines, then yes. Otherwise, not necessarily. =========================================================================WM has several times claimed that the standard bijection from the set of all binary sequences to the set of all paths of a Complete Infinite Binary Tree is a linear mapping from the set of all binary sequences regarded as a linear space over |R to the set of all paths of a CIBT.While the obvious mapping is easily shown to be bijective, it fails to be a linear mapping as WM describes it:> The isomorphism is from |R,+,* to |R,+,*. Only in one case the> elements of |R are written as binary sequences and the other time as> paths of the Binary Tree. Virgil is simply too stupid to understand> that.everal flaws in WM's claim that the identity map on  induces a linear map on 2^|N.  WM's flaws in making that claim work include, but are not necessarily limited to:(1) not all members of |R will have any such binary expansions,  only those between 0 and 1, so that not all sums of vectors will "add up" to be vectors within his alleged linear space of binaries, and (2) some reals (the positive binary rationals strictly between 0 and 1) will have two distinct and unequal-as-vectors representations, requiring that some real numbers not be equal to themselves as a vectors, and so that two such pairs of binary sequences can only map to a single real thus also only to a single path, so that the mapping cannot be a bijection, and (3) WM's method does not provide for the negatives of any of the vectors that he can form, so his "space" does not qualify as a linear space in that way, either.On the basis of the above problems, and possibly others as well that I have not yet even thought of, I challenge WM's claim to have linearly injected the set of binary sequences into the set |R or the image of the set of binary sequnces  in |R linearly ONTO the set of all paths.Note that while WM's model doe not achieve what he claims for it, there is another model, which a reasonably competent mathematician should be able to find, which does make the mapping into an isomorphism of linear spaces. I will produce this model when WM concedes his error, or at least no longer claims it is not an error.It is a shame that someone so obviously of limited ability at mathematics as WM should feel himself so driven to try and correct his betters.--
