E and Aalgorithms for finite arithmetic prime progressions and other sets
Thank you for forcing me to state things explicitly which were obvious to the people who saw my question in the past.

"I'd like to know about the algorithms which I am about to describe below." about the existing algorithms or the new algorithms which you can provide yourself.

All this is really irrelevant to the problem. I have added an endremark to my Question in its text.

Solving for 2 numbers that both add and multiply to the same known
Thus I think that this is a nice elementary school question, when it leads to a successful puzzle.

Solving for 2 numbers that both add and multiply to the same known
During a party at my place, I showed my fellow engineers from work that my HP programmable calculator multiplies in my hand while it was adding in their. They used the same calculator, with the same program. You input two fractions (pairs of natural numbers). You get one output number. But they were getting the sum while I was getting the product. Thus I claimed that my calculator is intelligent, and that it knew me, can recognize me.

Fixed points and universal maps for posets
@dominiczypen, thank you for kind words. I'd need to go back to my topic of the universal maps and universal morphisms. It's been half a century ago :)

from a circle to higher spheres
Once @Thomas (bravo!) said $\ B^3\times S^1\ $ the rest is easy. One may give a generalization of this too.
