Is there a tabulation somewhere of the isomorphism classes of distributive lattices $L$ with $|L|=n$ for small $n$? Google has not found me one.



Classification of small finite distributive lattices
I have the same problem to collect posets with certain properties and for distributive lattices I have the following solution which was good enough for my purposes.
Here is a sage program to obtain all distributive lattices (in form of their leq matrices) on $n$ points which works for $n \leq 9$ in the sage online cell <https://sagecell.sagemath.org/> and works for about $n \leq 14$ with sage with a good computer (and alot of waiting).



```
n=5;
P=Posets(n-2)
P=[p.with_bounds() for p in P]
L=[p for p in P if p.is_lattice() and LatticePoset(p).is_distributive()]
display(len(L))
U=[p.lequal_matrix() for p in L]
display(U)
display(L[2])

```

the display(L[2]) command displays a distributive lattice of your choice and
the len(L) command gives the number of distributive lattices on $n$ elements.
