I really don't know but thank you for your references. I will add them
in the next days to A115418 (maybe in the meanwhile some other
reference will come out).

If anybody is interested here are the minimal loops that I found:

http://www.mat.uniroma2.it/~tauraso/Loops/3-loop473.txt
http://www.mat.uniroma2.it/~tauraso/Loops/4-loop9641.txt
It is interesting to note that the minimal squareloop is unique.
On the other hand the minimal cubeloop is not unique.

Bye,
