You’d also be forgiven for not being able to correctly guess the astonishingly high number of different ways you could tie a tie, which a small team of mathematicians at the KTH Royal Institute of Technology in Stockholm have come up with. Using a mathematical process they used, the team determined that the number of ways to tie a tie is;

177,147
