Greechie Diagrams

This page presents some Greechie diagrams generated by Brendan McKay, Norman Megill, and Mladen Pavicic. Each diagram is connected and has only blocks containing three atoms.

Each file is a gzipped text file with one diagram per line. The name of the file indicates the contents: the number after the "v" is the number of atoms (vertices) and the number after the "e" is the number of blocks (edges). If there is no "e" with a number after it, all the diagrams with the specifed number of atoms are given in decreasing order of the number of blocks. The word "some" in the file name means that the collection for those parameters may not be complete.

The format of the files is that one diagram appears per line. The blocks are separated by commas and the last block is terminated by a period. The blocks are a list of atoms, using the one-character names "123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabc...".
