For each mechanism and purview it keeps every state of maximal intrinsic information and takes the first of greatest phi; among purviews whose phi ties (within 1e-13) it keeps the first in the iteration order of a Python set of index tuples; and a distinction enters the Phi-structure through the first of those kept ties that is congruent with the system's specified cause and effect states. Which tie comes first depends on the units' indices, so numbering the same units differently can change which distinctions are congruent, their purviews and states, and so the relations among them and Phi. PQRS in 0101 has many such ties. Run in a sandbox with no network under the authors' configuration, PyPhi itself gives 13 distinctions, 8,184 relations and Phi 391.247222 in the authors' order, 12, 4,088 and 209.844265 with the units reversed, and over all 24 orders nine values of Phi: 205.051271 (3 orders), 209.844265 (3), 210.905044 (1), 212.043744 (2), all with 12 distinctions, and 390.241709 (6), 391.247222 (3), 395.034703 (3), 396.095481 (2), 397.234181 (1), all with 13.
