Summary: In 1980, about 20 years after sequenceable groups were introduced by Gordon to construct row-complete latin squares, Keedwell published a survey of all the available results concerning sequencings. This was updated (jointly with Dénes) in 1991 and a short overview, including results about complete mappings and R- sequencings, was given in the CRC Handbook of Combinatorial Designs in 1995. In Sections 1 and 2 we give a survey of the current situation concerning sequencings. In Section 3 we consider some concepts closely related to sequenceable groups: terraces, R-sequencings, super sequenceable groups (also known as super P-groups) and the Gordon game. We also look at constructions for row-complete latin squares that do not use sequencings.
