One more catenary

Do you know an analytical solution of this problem - a closed chain on the horisontal cylinder?

Mathcad Prime 5 two sheets (Find & Minimize) in attach.

OR! No symbolic solution with catenary 🤔

May be there is one symbolic solution for this problem - a parabola, not a catenary!

I published an article about a chain on a cylinder in the article collection of the Institute of Mechanics of Moscow University. This institute employs people who calculated the flights of the first spacecraft - Sputnik, Jury Gagarin etc!

See please attach!
