I strongly support Nick's general principle that
one should name an object by the properties it does
have rather than those it doesn't:

X<n> is the space with Hurewicz dimension n
       (ie is (n-1)-connected). This usage is
       pretty firmly established by BU<6> etc.

BP<n> still has v_n

I don't know if Adams' use of
    X(m,n) (which would be better X[m,n])
and X(m, ... , \infty ) (which would be better X[m,\infty) )

in `On Chern characters and the structure of the unitary group'
in 1961 might have given rise to the X<n> type notation.

[Of course I would also advocate avoiding `non-negative numbers'
for `numbers >= 0' on the above general principle, but I know
this is more contentious!]
