859:. This was the toughest one to handle, because I don't want to list publications in the references section (implicitly saying that they're good references to the subject) only to say somewhere else that they're actually not so good, and I don't think we need to point fingers at authors of discredited theories. But I found a recent and impeccable source (Clagett) who attributes the "some other sources" claim more specifically to "many of the early Egyptologists" so I went with that as a direct quote. —

609:"isosceles sets, sets of more than three points in which every triangle is isosceles" Based on the definition provided in the reference, an isosceles set could have three points. This also does not make it clear where these triangles come from; consider rewording this to make it more clear that any three points in the set form an isosceles triangle.

How could he publish something in 1899? This is a clear mistake, at least unclear information, since there is no reference. If this refers to "Curiosa
Mathematica", then it has to be 1890. So I guess it is a typo.

Can we add the etymology of the word 'isosceles' here? Googling I found that it was "isos ‘equal’ + skelos ‘leg’". I think it aids understanding.
