1. What is the definition of Lie group framing, in simple terms?

2. Is the Lie group framing of spheres a particular type of Lie group framing? (How special is the Lie group framing of spheres differed from the generality of Lie group framing?)

3. Examples of Lie group framing includes:

• $\Omega_3^{fr}=\mathbf{Z}/{24}$ generated by a 3-sphere $S_3=SU(2)$ with the Lie group framing.

• $\Omega_6^{fr}=\mathbf{Z}/{2}$ generated by $S_3 \times S_3$ with the Lie group framing.

How do we construct the explicit class of $\mathbf{Z}/{24}$ and $\mathbf{Z}/{2}$ class of Lie group framing above?
