The list of record-typing 2, 3, 4, and 5-isogram sets (bisograms, trisograms, or more generally nIsograms) was augmented recently by a computer search of a database of isograms manually culled from Webster's Third. As with previous exercises, the words conform to Games Magazine criteria of acceptability. This particular database was weighted more heavily in favor of longer words, in an attempt to find the elusive 2.20 to go along with GUNPOWSERY BLACKSMITH. However, none was found! Though the database was large, it was by no means exhaustive; record-breaking specimens may yet exist.
