Quandle Colorings and Invariants of Knots in the Table

This website contains information on relations between quandle colorings and a few invariants of knots in the table.
This is a summary of observations made by W. Edwin Clark and Masahico Saito in 2012-2013.


Backgound material on quandles is available at the website
Quandle Cocycle Knot Invariants.

Our computations use results on quandle knot colorings posted at the website
Small Connected Quandles and Their Knot Colorings.

Computational outputs

The integer Lq_X (K) of a knot K for a finite quandle X is the ceiling of log_b (Col_{X}(K)),
where Col_X (K) denotes the number of colorings of K by X, and b=|X| denotes the order of X.
The following files contain the maximum values MLq(K) of Lq_X (K)
for 2977 knots K in the table with 12 crossings or less, over a set of 439 quandles X.
These 439 quandles consist of 431 RIG quandles (see the website on small connected quandles and their knot colorings )
and 8 additional larger quandles, Q[i], i=16, 18, 19, 20, 22, 23, 25 from of a family of 26 quandles that distinguish all 2977 knots.
None of the last 8 larger quandles is Alexander.
