As far as I know, there is no in-built function to do this. However, the information for groups of order 32 is available here:
http://groupprops.subwiki.org/wiki/Groups_of_order_32 For the group you have at hand, if you calculated the Hall Senior number, you hprobably also have information about the group up to isoclinism (in particular, the isomorphism class of the inner automorphism group and the derived subgroup), and some other invariants associated with the group. Using this information, you can run a search within GAP among the groups of order 64 and use that to figure out the GAP ID. Alternatively, if you have an explicit presentation of the group, you can use that to find the GAP ID.
