There are more than 100 characters in Game of Thrones, HBO's hit adaptation of George R.R. Martin's epic fantasy book series. With such an enormous cast, pinpointing the main protagonist can seem impossible ... unless you follow the math. According to a team of mathematicians, Tyrion Lannister (Peter Dinklage's character) is the true star of the show, The A.V. Club reports.

Andrew Beveridge, an associate professor of mathematics at Macalester College, and undergraduate student Jie Shan performed a network analysis on the third book in Martin's series, A Storm of Swords. They then studied the connections between characters to determine who is at the center of the narrative. Their findings were recently published in the Mathematical Association of America's journal, Math Horizons.

"Acting as the Hand of the King, Tyrion is thrust into the center of the political machinations of the capitol city," Beveridge and Shan concluded. "Our analysis suggests that he is the true protagonist of the book."

But not everyone is convinced that complex mathematical equations are an accurate way to determine the show’s main character. "We could point out the study only used book three, A Storm Of Swords, to conduct the study," Alex McCown of The A.V. Club wrote, "meaning it suffers from the same fallacious first principles as behavioralism when it comes to positing outcomes for absurdly large chains of reaction."

Still, whether you buy the study's conclusions or not, we can all probably agree that only Martin knows who the real protagonist is—and he's not telling.
