Comments

An n X n mosaic is an n X n array of the 11 tiles given by Lomonaco and Kauffman. The mosaic number of a knot K is the smallest integer n such that K is realizable on an n X n knot mosaic.

Here, we count the unknot as a prime knot.

Example

There are exactly 6 prime knots that are realizable on a 5 X 5 knot mosaic but not realizable on a 4 X 4 knot mosaic. Namely, these knots are 4_1, 5_1, 5_2, 6_1, 6_2, and 7_4 (see Table 1 of Lee et al.). Hence, a(5) = 6.
