didericis 256cbbf90a Complete n=28 census: 4 counterexamples among 1,204,737 min-deg-5 triangulations ...

Exhaustive enumeration at order 28 finished with exactly four maximal
planar graphs of minimum degree 5 lacking a plane diamond coloring,
out of 1,204,737 total. Adds the fourth counterexample's canonical
graph6 string and updates the figure caption.
