Here is a paragraph with some statements about the Gauge Symmetry Breaking from Georgi's book Lie Algebras in Particle Physics 2nd ed -- From Isospin to Unified Theories (Georgi, 1999) p.285.
Georgi wrote:

His claim is too quick. Can some experts explain which symmetry breaking pattern he is thinking of? In particular, he uses three Higgs fields in three representations:
24 should be the adjoint representation of SU(5).
5 should be the fundamental representation of SU(5).
45 should be EITHER the adjoint representation of SO(10) or some (what kind?) representation of SU(5).
question: How do we use representation 24, 5, and 45 to break from SO(10) to SU(5) to SU(3)×SU(2)×U(1)?
