A glider pair is two gliders traveling in the same direction with a specific spacetime offset. In a transceiver, the preferred term is tandem glider. For several years, glider pairs on lanes separated by 9 or 10 half diagonals were the standard building blocks in Geminoid construction arm recipes. In more recent 0hd and single-channel construction toolkits, all gliders share the same lane, but glider pairs and singletons are still important concepts.
