As Bettina Eick pointed out, all the groups of these orders are not available,
and it is suggested to restrict to the groups really needed. In fact, some
classes of groups can be computed more easily.
I have lists of the groups of orders 2^10, 3^7, 3^8, 3^9, 5^7 and rank (number
of generators) 1 and 2, and of order 5^6 and rank 1, 2, 3, and 4.
These lists were calculated with the GrpConst package, and a few weeks of CPU
time. They include all the groups of the given orders and ranks, but are not
duplicate free. At the moment, these lists are roughly organized as a gap4.3
Calculating the groups of higher order in this way would require months of
machine time, and calculating groups of higher rank would require to solve
problems related to the memory management.
If you are interested, I can give you these lists.
