What 4 fighters have fought each other in every possible combination?

Just wondering how often this happens.

Oscar - Shane - Fernando Vargas - Wilfredo Rivera

Would rather have Tito Trinidad in place of Wilfredo, but oh well.

That's the only one that comes to mind at the moment.

You can also replace Rivera with Mayorga.

Margarito, Martinez, Williams, and Cintron too. And obviously Duran, SRL, Hagler, and Hearn.

Mayweather- Corley- Judah- Cotto.
