Re: Alternating Periodic Sequences

I now count three cases in which there is an endless repetition of the same yerm. Quite surely these are the only possibilities of this scheme.

17ths = 21, 22, 21, 22, 21, 22, 21, 22, 21, ... ( 33 cells )
146ths = 3, 2, 3, 2, 3, 2, 3, 2, 3, 2, 3, 2, ... ( 301 cells )
244ths = 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, ... ( 161 cells )

To calculate the mean yerm

mean yerm of 17ths = 1 / [ ( 731 / Y ) - 2 ]
mean yerm of 146ths = 1 / [ 2 - ( 730 / Y ) ]
mean yerm of 244ths = 1 / [ ( 732 / Y ) - 2 ]

or ( C = cell )

mean yerm of 17ths = 1 / [ ( 43 / C ) - 2 ]
mean yerm of 146ths = 1 / [ 2 - ( 5 / C ) ]
mean yerm of 244ths = 1 / [ ( 3 / C ) - 2 ]
