Let's say :

for two opposit "pick", this can be done with the difference of one
sphere and 4 tori from a larger sphere. So it makes 3 times this : 12
tori and 6 spheres. 
With a nice texture over, this should make the trick ? no ?

Denis.

I only used 1 shape type in the CSG. All the same size.

And its not at all as complicated as you describe above.

I'm probably wrong, but I'll make a stab anyway... 24 torii differenced from
3 torii?

Sorry. This also wrong.

The solution is simpler!

Keep trying :)

=)

Nope - I wouldn't know how to do that!

Some of the previous repliers have guessed
the shape but not how many.

Just an intersection of 4 torii.

Like this:

// ============================================================

#macro Quadra(Thing)

  #local Angle = 180 - degrees(acos(1/3));

  object { Thing rotate 60*y }
  object { Thing rotate Angle*x }
  object { Thing rotate Angle*x + 120*y }
  object { Thing rotate Angle*x - 120*y }

#end // macro Quadra

#declare aTorus = torus { 2.445, 2 }

#declare StrangeShape =
intersection {
  Quadra(aTorus)
}

/*
#declare StrangeShape =
merge {
  Quadra(object { StrangeShape translate 3.95*y } )
}
*/

object {
  StrangeShape
  pigment { color Yellow }
}

// ============================================================

Also try to remove the commented code
