@shermanium is a tag used by artists (such as Ciara Zugay) in the context of brush lettering and calligraphy. The "paper" you're looking for might be a specific artwork, post, or template shared by that user.
The search for is more than a quixotic quest for a super-metal. It is a tribute to the engineering philosophy of robustness over perfection. The M4 Sherman wasn't the best tank of WWII, but it was the right tank. Shermanium, in spirit, is the right metal. Whether it emerges from a high-entropy alloy laboratory in Maryland or remains a myth debated on wargaming forums, the term has earned its place in the lexicon of engineering excellence.
