comment Complexity class notation
Okay, I see! The thing that bothered me most was the multiplication between sets and elements of the sets - but this is obviously well-defined so should be no problem. Thanks!

comment Can't argue with success? Looking for “bad math” that “gets away with it”
I wonder what kind of numerical system we could build out of this...

comment correct rotation and translation matrices
Okay, I've been trying to fix my program, recalculating and recalculating.. Always coming to this result. Something seems wrong though, my program keeps given faulty results..

Yes, the determinant is $+1$ now.

comment correct rotation and translation matrices
I tried two different methods so far: 1. multiply rotation matrices $R_x$, $R_y$ and $R_z$ and 2. put the components of the $a^\prime_i$, calculated in $a_i$ in a matrix. 3. mess around with a graphical program, I think that's were I got this. Was kind of busy so might have messed things up.

Updated the matrix to one that has better results

Ok I know for sure the matrix $M$ is wrong! Also for inverse transformations one should take the inverse and not the transposed as I have done. Some help on the correct transformation matrix would be great. Also, should I first rotate or first shift?
