    in the bosonic case and in the superstring 10D case it is 16 colours.

    Here at PF we have 26 smilies. one for each parameter in the standard model

    :rolleyes: :rofl: :approve: :yuck: :cry:

    :frown: :bugeye: :eek: :uhh: :shy:

    :grumpy: :!!) :mad: :wink: o:)

    Hi arivero,

    Your slow post [not Haloscan] to the Reference Frame thread above with Lubos' response brings sequences to my perspective.

    Were an 8 to accompany the 5, 13 then Fibonacci numbers come to my mind.

    I would bet for a 9. The point is that 10-dimensional and 26 dimensional strings have the same signature module 8. The signature is number of spatial dimensions minus number of time dimensions, so 9-1=8 or 25-1=24. The 25-1=24 is the origin of the work of Borcherds you mentioned in other thread.

    In the middle we have 17-1=16, so 18 dimensions and then some unknown object with a group SO(2^9).

    But speaking of sequences, I found the one of hexagonal numbers, hidden in my "consider QCD" post.
