^ Subject: MOP, a new GAP3 share package

Dear Members of the GAP Forum,

It is a pleasure to announce the new GAP3 share package


by Ulf Juergens and Gerhard Roehrle.

MOP is designed to compute upper bounds for the modality of the
action of a parabolic subgroup P (of an algebraic group G) on the
Lie algebra of its unipotent radical.

MOP can be applied if G has a simply laced Dynkin diagram.

Since MOP uses the CHEVIE share package of GAP3, it is not
available as a GAP4 package.

MOP can be obtained from the web page


Questions concerning the package or its installation should be
addressed to


or to
