How to? Rotate multiple shapes simultaneously on different axes

[FudgeFlakeNut]

Okay, I started with a Seripinski Tetrahedron with the following values for Position:

     Holon 1: 45, 45, 45

     Holon 2: 45, -45, -45

     Holon 3: -45, 45, -45

     Holon 4: -45, -45, 45

I figured that would make the rotation easier. 

I thought that for an angle R the rotation would then be:

     Holon 1: R/sqrt(3), R/sqrt(3), R/sqrt(3)

     Holon 2: R/sqrt(3), - R/sqrt(3), - R/sqrt(3)

     Holon 3: - R/sqrt(3), R/sqrt(3), - R/sqrt(3)

     Holon 4: - R/sqrt(3), - R/sqrt(3), R/sqrt(3)

But that was not right, apparently. Here's what I got when I tried R=60:

It looks like it's angling out of its axis in places where it should stay in line. I'm not sure where I went wrong. Here is the Xep:
