Notation commands are not easy to write correctly, as Tutorial on Notation on Mathematica 12.2 document explains. In my (short) experience, the easiest is to put all the Notation commands that you will use at the beginning of your notebook. Alternatively, create a notebook file, say EosNotations.nb under the Eos3.3 directory, put all your rotation commands, and read them by:

<<“EosNotations.nb”;

So the header of your file will be

<< “EosHeader.m”
