I just want to ask two questions about the demonstrations of the conjectures stated around this project.

1) I am totally unable to do it myself, but wouldn't it be possible to prove conjecture (10) by a method similar to the one used for conjecture (2) ? (see henryzz's post #476 and warachwe's post #480).
Indeed, 2^12-1 = 3^2*5*7*13 and we do have the 13 which preserves the 7 for the second iteration, except perhaps for some values of k that I did not examine, but the whole problem is precisely there, isn't it ?

2) At the end of the quote below, Alexander says: "(the composite ones will be harder)".
But does this mean that no one knows how to do such demonstrations yet, or does it just mean that we know how to do them, but that it is very long and tedious ?
