  This text is an appendix to our work "On the growth of Kronecker
coefficients", arXiv:1607.02887. Here, we provide some complementary theorems,
remarks, and calculations that for the sake of space are not going to appear
into the final version of our paper.
  We follow the same terminology and notation. External references to numbered
equations, theorems, etc. are pointers to arXiv:1607.02887.
