The 62 quads

Below follow the 62 quads or sets of 4 octominoes that make up each node in the network. The quads are numbered from 1 to 62, the octomino labels being the final 4 numbers in each row. To discover the shapes corresponding to each label click on 'The 61 Octominoes'. More interesting for research purposes is the number in the second column, which records the row number in file quads+tails.txt that is headed by the associated quad. For example, the top row shows that the 4 octominoes numbered 170, 195, 272 and 378 (or quad 1) appear in first position in row 544 of file quads+tails.txt. Serious investigators will soon discover the utility of this pointer.
