As part of my enumeration of the Bol loops of order 16 with nontrivial centre, here I list just the 316 loops which are non-associative with exactly eleven involutions. Please see the parent page for notation, including my conventions for naming of loops and table entries. I would appreciate an email message () from you if you have any comments regarding this list.
Three loops in this category have |Z(L)|=1, namely
Also six loops in this category have |Z(L)|=4, namely
The remaining 307 loops in this category all have |Z(L)|=2 and so the graph Comm(L) is defined. This graph is displayed as black-on-white if it has at most 10 edges; otherwise its complement (which has at most 10 edges) is displayed as white-on-black. In either case, isolated vertices are not displayed.
No. | Comm(L) | |C(L)|=2 | |C(L)|=4 | |C(L)|=6 |
