```Or you can simply transpose the tenors together FCH by the rows of the plain course and then transposing the tenor back to home (although it wonâ€™t give you the incidence)

e.g. for B falseness (24365)

2345678 = 2436578
3527486 = 3254786 = 5372648
5738264 = 5372864 = 3256748 (which is 2365478 backwards)

Etc.

I spent a large amount of time on this when I was young and keen and proudly showed Roger Baldwin the results only to be told that they were available in the back of composition 502.

Or if you don't have the time (or inclination) the Method Master program will extract FCH's. This includes split tenors on eight bells and the incidence. It will also do inter-method falseness.
