We give a syntactic view of the Sawada-Williams (σ,τ)-generation permutations. The corresponding sequence Seqn στ-operations length n!−1 is shown to have compact description size Θ(n2) in terms straight-line programs. Using description, we design almost linear time ranking and unranking algorithms.

Individual human adenoviruses (Ad) ~ vary in their tumorigenic potential in rodents. Group A serotypes induce tumors with high efficiency, while those belonging to the group C are nononcogenic (1). This phenomenon was originally thought to be a reflection of differences in their immunogenicity (2). Isograft transplantation experiments have shown, however, that immunization with both highly onco...
