Query: The ABCDEFG of Instantons and W-algebras   For arbitrary gauge groups, we check at the one-instanton level that the
Nekrasov partition function of pure N=2 super Yang-Mills is equal to the norm
of a certain coherent state of the corresponding W-algebra. For
non-simply-laced gauge groups, we confirm in particular that the coherent state
is in the twisted sector of a simply-laced W-algebra.
