Digital images with 4-adjacency, up to isomorphism

These are some results of the enumerations described in the paper "Some enumerations of binary digital images" by Chris Staecker. Visit the parent page for code and a machine-readable version of this list, and to see the other lists of enumerations.

Here are the total counts for the images, where n is the number of points. Only connected images are listed.

n 1 2 3 4 5 6 7 8 9 10 11 12
Total images 1 1 1 3 4 10 19 51 112 300 746 2042
Pointed-irreducible images 1 0 0 0 0 0 0 1 0 1 0 1
Irreducible images 1 0 0 0 0 0 0 1 0 1 0 1
Rigid images 1 0 0 0 0 0 0 0 0 0 0 0

In each image a minimal irreducible subset is colored blue. As you can see, almost all of these images reduce to a point.
