thankyou for making this page, whoever did. The trouble I am having with it is those unaware of degree level maths facts and jargon have to spend ages looking up other pages. I often have this problem with maths pages of Knowledge. Can someone please help, because fractals are pretty and I would like

And by the way, as is well known, any number whose binary expansion ends in a sequence of all 0's can be re-expressed in a binary expression ending in a sequence of all 1's, and vice versa. SO: Do both sequencs of binary coefficients give the identical p_x ? Whether the answer is Yes or No, this

But this is the same thing. de Rham himself gives both of these constructions in his original paper (the 1957 paper cited in the article). He spends some time computing the length of the cut-polygonal-arc construction, as that is the construction where it is easy to compute the length.

so one has to fiddle about to re-obtain the above relationships. Note that ALL of these curves have the period-doubling symmetry, NOT just the question mark. That is, there are appropriate variants of S and T that describe ALL of these curves!
630: 2672:, so the points belonging to the curve verify that (S(x),y/2) and (T(x),(1+y)/2) are also on the curve. Then the following mappings generate the 2-dimensional curve corresponding to the graph of the Minkowski's question mark function: 632:, maybe saying a word about this construction, because the composition of an infinite sequence of functions is not something natural (and the subject is not even mentioned in the linked page about function composition), 2984:
expression most often design "curves are obtained from a polygonal arc by passing to the limit in repeatedly cutting off the corners: at each step, the segments of the arc are divided into three pieces in the ratio

converges uniformly (because of contraction mappings) toward a continuous curve (because of uniform convergence), that we will define to be the De Rham curve.

denotes function composition. It can be shown that . The collection of points p_x, parameterized by a single real parameter x, is known as the de Rham curve.

Only then should the number x be defined and described as a way of parametrizing the collection of points, which can now be called {p_x}.

But this would be long and technical. A more intuitive solution could be to:

Additionally, I think this article lack of historical background.

I think you're right about the order, to be rigorous we should:
