[For the entire collection see Zbl 0686.00006.]
The author studies versal deformations of the Galois representations associated to the weight 12 cusp form \(\Delta\) as an example of the general theory of deformations of Galois representations attached to modular forms and elliptic curves. Many explicit examples are given.
