COMMENTS

The values A114611(j) for those starting values j of the RATS mapping x->A036839(x)

which end in cycles that cannot be reached starting from any smaller j.

EXAMPLE

a(1)=A114611(0). a(2)=A114611(j=3)=8 with a cycle of length 8 shown in A066710.

A114611(j=6)=8 does not contribute because the cycle is the same as reached from j=3.

a(3)=A114611(9)=2 with a new cycle of length 2 shown in A066711.

A114611(j=12)=8 does not contribute because the cycle is the same as reached from j=3.

A114611(j=15)=8 does not contribute because 15->66->123 is the cycle as reached from j=3.

A114611(j=18)=2 does not contribute because the cycle is the same as reached from j=9.

A114611(j=21)=8 does not contribute because 21->33->66 reaches the same cycle as started from j=3.

a(4)=A114611(j=29)=18 .
