The 0R column indicates the connections required to make the logic gate in the given row, with no relays. Clear can be made by leaving Q+ and Q- disconnected, while mark can be made by connecting Q+ and Q-. No other gates can be made in this way, since there are no inputs.
The 1R column is for gates which can be made using a 1-input function. The listed contacts are where the output is read from (named Q+ and Q-). The single input comes from the coil.
The 2R columns (000-111) specify the dual-relay configuration needed to make the specified logic gate. 000 through 111 are the wiring connections (NC COM NO) that should be interconnected - for example 101 means connect each relay's NC together, connect their NO's together, but leave COM unconnected. The table data has the points at which the output may be read from (in the form of an open or closed circuit, as with 1R). There may be multiple configurations which make the same gate.
So far the dual-relay configuration for A+B' and B+A' has not been found.
