Does a complete list of unique synergies exist?

With all new champions being released with unique synergies that essentially buffs older ones, I was wondering if any list has been compiled that has the description and what champs are that the synergy affects. I know this list wouldn't be essential, but I think a list like this would help both newer players and veterans get a idea of ways that they can improve their champs. If a list like this does exist, can someone post a link? Thanks
