### M Theory Lesson 145

Thinking about pairs of pants, we see that the twistor moduli surfaces are made of either four pants, or three pants, or two pants, although they are not entirely glued up like the Klein surface. If we like, we can make a $3 \times 3$ matrix of such spaces, since spaces are just a kind of higher dimensional groupoid.

Hi Kea, it took me a while to figure out the equivalence of the four pants diagrams... I think your lessons on M-theory belong to a book, you have so much material out there already!

Cheers,

T.
