%N a(n) is the number of column convex polyglasses (polyiamonds which need only touch at corners) with n cells.
%C A polyglass is column convex if the intersection of its interior with any vertical line through the centers of the cells is connected.
%H Adam Gruber, <a href="https://devweb3000.cis.strath.ac.uk/~xpb16190/LatticeAnimals/LatticeAnimals.jar">Java program to count lattice animals</a>.
%e There are four triglasses that are not column convex. So a(2) = A319324(3) - 4 = 84.
%Y Cf. A319324 (fixed polyglasses), A319325 (row convex polyglasses), A319323 (column convex polyiamonds).
