In LSL, quaternion multiplication is written down in reverse order as in maths :

  Q2 * Q1   (LSL)

is the same as

  Q1 . Q2    (maths)

Perharps that would deserve a word of explanation here.

This text has two shemas at the end. If you look well at it, the 90° rotation in the first schema and in the second schema are supposed to be opposite (once in z direction, the other time in -z direction) but the pink arrow materializing the rotation is the same.

It's the first schema that is correct (LSL follows right-hand rule for direction of positive rotations)

So what do we do to fix this page? (Cathy Pfeffer) [PS my interpretation of z-1Qz problem was wrong, rephrased. See above]
