ABSTRACT: It is proved that for a strongly continuous semigroup T on the Frechet space omega of all sequences, its generator is a continuous linear operator A
in L(\omega) and that, for all x in omega and t 0, the series exp(tA)x:=sum_{nu=0}^inf y frac{t^nu}{nu!}A^nu x converges to T(t)x.

This solves a problem posed by Conejero.
