horn torus entity
 

 
x = r·(1 − cosφ)·cos(φ2/2π) 
y = r·(1 − cosφ) · sin(φ2/2π)
z = r · sinφ        

 
r = r1·φ / 2π for r > r1
φ = 2π when r = r1 *)   
φ < 2π doesn't occur ! 
 
φ is the poloidal horn
 torus angle, r in the graphic above is quite to scale
(increase is faster than in the
 2nd graphic, r <
 r 1), depicted is the section
between 10 revolutions per 1 rotation  and
 ∼7 rotations per 1 revolution
(for explanation click image)
 
 
 
*) r1 signifies the
standard dynamic horn torus, the 'μ-sterious'
mirror between
 'infinite outer world', consisting of electrons and photons, and the 'small inner world' of
hadrons and
 infinitesimal infinity.
 
Important note 1 in this context: the widely unknown infinitesimal infinity has the
 same cardinality as our known large universe (i.e. nuclei comprise whole universes).
 It's worth to think about that!
 
Note 2, equally imperative: horn torus depictions are allegoric only, their purpose is
 to symbolise mathematical particle properties - they don't occur as objects in
 our  familiar 3-dimensional space.
 
Dynamic variation of poloidal revolution and toroidal rotation, combined with
 alteration of size, can be expressed smartly by complex and hypercomplex numbers
 (quaternions, octonions, ...) - but
 
to describe the whole dynamics as abstract physical processes, including the
 interaction of intertwined nested horn tori, seems to be a task, which is
 not manageable by conventional
mathematics,
 
so, in this regard, the author is not ready yet :-(
