Is 18:82 a valid ratio for aqua regia?

[Here](https://medical-dictionary.thefreedictionary.com/nitrohydrochloric+acid) it writes that nitrohydrochloric acid (possibly Aqua Regia) is of the ratio of $18:82$, which is $1:4.56$ in a simpler form. On Wikipedia and every other source i found the ratio $1:3$. So what's the truth behind this?


Also is Aqua Regis a valid way to call the mixture? On [Wiktionary](https://en.wiktionary.org/wiki/aqua_regis#English) it says that this is a synomym of Aqua Regia but why would it have such a different ratio then?
