simple, there are many symetries in 3 main planes. So I used arcs rotated 45° from the main planes and I generate a pentagon which was mirrored and rotated many times.
At the end there are 24 pentagons and 8 hexagons so 32 faces, 54 points/vertex and 84 edges.
It could generate some others tessalation styles

ength is applied to particle b, and the same vector multiplied by -2*BendStrength is applied to a and c
Hope that helps. I was thinking of changing this input slightly for the next Kangaroo release, because I realize it can be a pain if you want bending stiffness of a curve to be independent of the number of points used, but I'll make sure to clarify any changes when I do update this.

an that HashCodes well ... since they are "unique" per item (even if this - for the one reason or the other - is created at the same location with that) I barely can see how one can use them in order to get rid if "equal" items (Lines in this occasion).
On the other hand ... well ... using HashSets sampling the Line center and testing length and direction ... well ... this works but why bother? > if you are not doing business with code (thus you need this "check" internally) > use the Kangaroo1 component.
That said the topic of "equality" is rather huge and most people are confusing a lot of things on that matter: for instance a point not equal to another ... well ... that's rather simple but a brep "not equal" with some else ... this is not that easy (if it's solvable).…
