BibTeX entry

 @misc{ wiki:xxx,
   author = "Mundinix Informations",
   title = "OPA --- Mundinix Informations{,} ",
   year = "2016",
   url = "http://www.mundinix.com/wiki/index.php?title=OPA&oldid=41",
   note = "[Online; accessed 25-October-2026]"
 }

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 = "Mundinix Informations",
   title = "OPA --- Mundinix Informations{,} ",
   year = "2016",
   url = "\url{http://www.mundinix.com/wiki/index.php?title=OPA&oldid=41}",
   note = "[Online; accessed 25-October-2026]"
 }
