I've been working on a classification of Bol loops of small order. Here is a list of the 8 Bol loops of order 20. This includes the five groups, one non-associative Moufang loop, and two non-Moufang (and non-associative) Bol loops. The latter two examples are isotopic, but the other six are G-loops. The completeness of this list follows from Burn (1981).
I have made available
In listing elements of the commutator (resp. associator) subloop of each of these loops, we have printed in italics
any elements which are not actual commutators (resp. associators). (I have not checked whether this
phenomenon occurs in any of the loop of order 20.)
The Five Groups: 20.1.20.0, 20.1.2.0, 20.3.20.0, 20.11.2.0, 20.5.1.0
The non-associative Moufang Loop: 20.15.1.1
The non-Moufang (non-associative) Bol Loops: 20.7.3.0, 20.15.1.0
