The order 3125 is part of GAP's SmallGroup library. Hence, any group of order 3125 can be constructed using the SmallGroup function by specifying its group ID. Also, IdGroup is available, so the group ID of any group of this order can be queried.
Further, the collection of all groups of order 3125 can be accessed as a list using GAP's AllSmallGroups function.
Here is GAP's summary information about how it stores groups of this order, accessed using GAP's SmallGroupsInformation function:
gap> SmallGroupsInformation(3125); There are 77 groups of order 3125. They are sorted by their ranks. 1 is cyclic. 2 - 38 have rank 2. 39 - 70 have rank 3. 71 - 76 have rank 4. 77 is elementary abelian. For the selection functions the values of the following attributes are precomputed and stored: IsAbelian, PClassPGroup, RankPGroup, FrattinifactorSize and FrattinifactorId. This size belongs to layer 4 of the SmallGroups library. IdSmallGroup is available for this size.
