Function 4b15g_4 is one of five different reduced 4-bit reversible functions requiring 15 NOT, CNOT, Toffoli, and Toffoli-4 gates in its optimal implementation. This specification may be used to generate 23 other 4-bit functions requiring 15 gates via a combination of simultaneous input/output relabeling and inversion.
