Returns the 4 points (resp lines) and affects the last argument,
such as the 4 points (resp lines) are in a harmonic division.
harmonic_division(Pnt or Line,Pnt or Line,Pnt
or Line,Var)
Draws an icosahedron with center A, vertex B and such that
the plane ABC contains one vertex among the 5 nearest
vertices from B.
icosahedron(Pnt(A),Pnt(B),Pnt(C))
Returns 1 if the 4 points are in a harmonic division and 0
otherwise.
is_harmonic(Pnt or Cplx,Pnt or Cplx,Pnt or
Cplx,Pnt or Cplx)
Returns 1 if the circles build a beam, 2 if they have the same
center, 3 if they are the same and 0 otherwise.
is_harmonic_circle_bundle(Lst(Crcle))
Returns 1 if the lines have a common point, 2 if they are
parallels, 3 if they are the same and 0 otherwise.
is_harmonic_line_bundle(Lst(Line))
Returns 1 or 2 if the 4 points (or the object) build a rhombus
(2 for a square) and 0 otherwise.
is_rhombus(Pnt or Cplx,Pnt or Cplx,Pnt or
Cplx,Pnt or Cplx)
Returns the size of a list, a string or a sequence
length(Lst or Str or Seq)
Draws the horizontal line y=a.
