Hi Russ, Let me use an example. Suppose there are four (k=4) RBridges: RB1, RB2, RB3 and RB4. Their SystemIDs are 001, 010, 011 and 100. Suppose the LAALP ID is 1. Then the four concatenations are 0011, 0101, 0111 and 1001 while the four 'mod' values are 3, 2, 3, 1. So, these are not always the same, even for the same LAALP ID. For the above example, the sorted list would be (RB4, RB2, RB1, RB3). Here, RB1 and RB3 have been sorted using their unsigned-integer-SystemID as a tie-breaker. Have I cleared the doubt?
