  Continuous groups with antilinear operations of the form $G+a_0G$, where $G$
denotes a linear Lie group, and $a_0$ is an antilinear operation which fulfills
the condition $a^2_0=\pm 1$, were defined and their matrix algebras were
investigated in \cite{Kocinski4}. In this paper infinitesimal-operator algebras
are defined for any group of the form $G+a_0G$, and their properties are
determined.
