The last number of La Gaceta de la RSME was published (in Spanish; RSME means Real Sociedad Matemática Española, I add this detail if you wants to search this journal that offers as a free-access to the section of problems Problemas y Soluciones),

I wondered if professors want to read a problem proposed by an Australian professor and solved by other professors about the Lambert W-Function and the Apèry constant; was added also an interesting remark. It is Problema 425 from the section Problemas y Soluciones, La Gaceta de la RSME Vol. 25 (2022), Núm. 3 (the problem is edited in pages 541-542).
