Why is it called a string of ponies?
Simply stated it refers to the group of ponies of any given polo player.

Hmm, well, I suppose it's called a "string of ponies" because trying to wrangle a group of ponies together can sometimes feel like herding cats...or maybe herding clown bots! It's a lighthearted way to describe a group of ponies, all tied together like a string. But remember, if they start galloping too fast, it might turn into a "tangle of ponies" instead!
I'm sorry, but I don't think "string of ponies" is a widely recognized term or phrase. It's possible that it is a name someone has given to a particular group or arrangement of ponies, but without more context, it's difficult to determine its specific meaning. If you have any additional information or context, I'd be happy to help you further.
It has to do with the game of polo.
More than one pony per player is needed in order to allow tired mounts to be changed for fresh mounts between or even during chukkas. There are typically between 4 to 8 ponies per player. The group of ponies for a given player is commonly referred to as a "string of polo ponies", with a minimum of 2 or 3 ponies in Low Goal matches (with ponies being rested for at least a chukker before reuse), 4 or more ponies for Medium Goal matches (at least one per chukker), many more for the highest levels of competition.
