* 3-of-6 code extension: The excess-3 code is sometimes also used for data transfer, then often expanded to a 6-bit code per [[CCITT]] GT&nbsp;43&nbsp;No.&nbsp;1, where 3 out of 6 bits are set.<ref name="CCITT_1959"/><ref name="Steinbuch_1962"/>
* 4-of-8 code extension: As an alternative to the [[IBM]] [[transceiver code]]<ref name="IBM_Transceiver"/> (which is a 4-of-8 code with a [[Hamming distance]] of 2),<ref name="Steinbuch_1962"/> it is also possible to define a 4-of-8 excess-3 code extension achieving a Hamming distance of 4, if only denary digits are to be transferred.<ref name="Steinbuch_1962"/>
