[GAP Forum] hall-senior number vs small group id

[sumeyra uskudar]

dear forum,
is there a function in gap (or anywhere) which can give the small group id
of a group when we give the hall-senior number? or visaversa?

Indeed, I need the subgroup structure of the group of order 64 which has
Hall Senior number 187. but I can not get the small group ID from anywhere
thus it is hard to define it in GAP.
