Note for anyone using python for this: the Johnson algorithm is implemented as simple_cycle in networkx. An simple cycle, or elementary circuit, is a closed path where no node appears twice, except that the first and last node are the same. Then the simple cycles A-B-C-A, B-D-C-B and A-B-D-C-A are represented as (1, 1, 1, 0, 0), (0, 0, 1, 1, 1) and (1, 1, 0, 1, 1).
