[seqfan] Spinors and Bott periodicity

[Charles Greathouse]

I was watching a video on quantum mechanics and I came to this part
http://www.youtube.com/watch?v=Tw8w4YPp4zM&t=38m5s
where John Baez discusses spinors, vectors, and division algebras. There
seems to be an integer sequence here, to wit:
1,2,4,4,4,4,8,8,16,32,64,64,64,64,128, ...
but I don't understand it well enough to add the sequence. Can anyone help?
