BibTeX entry

 @misc{ wiki:xxx,
   author = "Rosetta Code",
   title = "Knuth's power tree --- Rosetta Code{,} ",
   year = "2023",

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Rosetta Code",
   title = "Knuth's power tree --- Rosetta Code{,} ",
   year = "2023",
   url = "\url{https://rosettacode.org/wiki/Knuth%27s_power_tree?oldid=352720}",
   note = "[Online; accessed 20-April-2025]"
 }
