Graph and chains ...

For a given group and supergroup the program SUBGROUPGRAPH will give the
graph of maximal subgroups that relates these two groups and, in the case
that the index is specified, all of the possible chains of maximal subgroups
that relate the two groups will be shown.
Also, when the index is specified there is a possibility to obtain all of
the different subgroups of the same type.
As an input data you should give (or select) the numbers of the group and the
subgroup, and the index.
How to obtain a valid index ?
