    expanded the Idea-section with some lines on the algebraic motivation for SU(5)SU(5)- and Spin(10)Spin(10)-GUTs, with specific pointers to page and verse in Baez-Huerta 09 for details.

    in the process I introduced sub-sections to the Idea-section and re-shuffled the previous material just slightly, for better logical flow.

    in the section on “SO(10)-GUT” I have added this:

    The exact gauge group of the standard model of particle physics (see there) is isomorphic to the subgroup of Spin(9) \subset Spin(10) which respects a splitting 3\mathbb{H} \oplus \mathbb{H} \simeq_{\mathbb{R}} \mathbb{C} \oplus \mathbb{C}^3 (Spin(9)#Krasnov 19).
