As part of my enumeration of the Bol loops of order 16
with nontrivial centre,
here I list just the 508 loops which are non-associative with exactly nine 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.
One loop in this category has |Z(L)|=1, namely 16.9.8.3. The remaining 507 loops in this list 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 | |C(L)|=8 |
