1,701,936 unique knots (and counting) #megafavnumbers
#megafavnumbers Talking about my favorite number over 1,000,000. We currently know about the first 1,701,936 different kinds of knots. There are a lot of math youtubers making high-quality, well-edited videos about their favorite big number. This...might not be one off them. The two times

This knot is very useful for adjusting tie downs quickly and easily. For example, a tarp could be held down by a series of these knots and be made very tight so the wind cannot make it rise, and easily be removed simply by sliding the knots later. A taut line knot is also used to keep larg

Non-Orientable Knot Genus and the Jones Polynomial - Efstratia Kalfagianni
Efstratia Kalfagianni Michigan State University October 20, 2015 https://www.math.ias.edu/seminars/abstract?event=89714 The non-orientable genus (a.k.a crosscap number) of a knot is the smallest genus over all non-orientable surfaces spanned by the knot. In this talk, I’ll describe joint
