Dear GAP-forum,

I have a pleasure to announce a set of codes for testing some
subgroup embedding properties like as abnormality, pronormality, etc.
It seems to be useful tool for researchers in/coming across the area
even although programs work satisfactory just for small groups. The
file "embedsub.g" can be found out on ftp server of LDFM, RWTH Aachen:

ftp.math.rwth-aachen.de/pub/incoming/embedsub.g

It contains a brief description of the codes complemented with
information about basic concepts and references. In addition,
the author would be glad to send his unpublished English survey
(cited as [8] in the description) to any interested person.

Any suggestions and comments with respect to that set of codes
are welcome, preferably by e-mail.

Best wishes, Vitaliy Mysovskikh
