• We give a simple formula for the essential dimension of a finite pseudo‐reflection group at a prime p and determine the absolute essential dimension for most irreducible pseudo‐reflection groups. We also study the ‘poor man's essential dimension’ of an arbitrary finite group, an intermediate notion between the absolute essential dimension and the essential dimension at a prime p.
