Rolfsen's Knot Table

Definition

Rolfsen's Knot Table is a systematic classification of knots developed by Dale Rolfsen in the 1970s, designed to provide a comprehensive reference for researchers studying knot theory. This table organizes knots based on their crossing number and type, allowing for easier identification and comparison of different knots. It became a crucial resource in the historical development of knot tables, influencing subsequent work in the field of knot theory and topology.
