After Dan's (a), I propose to define a second function (b): (a) M=(3N+1)/2^K then P=(3M-1)/2^K. (b) M=(3N-1)/2^K then P=(3N+1)/2^K. Interesting to see very similar properties: (a) two families, 1 and 17 (-> 19 -> 43 -> 97 -> 109 -> 61 -> 17...) (b) two families, 1 and 13 (-> 29 -> 65 -> 73 -> 41 -> 23 -> 13...) Similar percentages 1:17 for (a) and 1:13 for (b)??? Soon a report on the 2 functions from 1 to 10,000,000,000. Christian.
