The results from the Section Peano Curves
and Semigroup ability were a part of a very first version of the paper .
Because Giuseppe Peano (1858-1932) was the first to discover one of the filling curve constructions, space-filling curves in 2-dimensional planes are sometimes called Peano curves
. Some of the most celebrated are the Hilbert curve and the Sierpimki curve .
Using Peano curves for bilevel display of continuous-tone images.
This would enable the construction of other forms of space-filling curve, such as the Peano curve.
