I am searching for the Number of labelings of symmetric hexagonal tilings
If the hexagon is of the form P(n,n,n) then the coefficients can be found here A217311
I am looking for the coefficients of P(4,2,4)
After doing some research I found P(2,3,2),P(3,3,4),P(3,4,4)... and some others but not the one I am looking for
I took the img from https://arxiv.org/pdf/cond-mat/0004145.pdf
mathworld states that
http://mathworld.wolfram.com/PlanePartition.html
Using the above formula I can only calculate the first term which is 1764.
How can i find the other terms?
can anybody help me find the coefficients for P(4,2,4)?
thanx
