The sequence seems to give the least common multiples also for the permutation A126315/A126316, but with a(3)=6 instead of 3.

A127282 Number of fixed points in range [A014137(n-1)..A014138(n-1)] of permutation A126315/A126316.

Note that a(12)/A000108(12) = 207882/208012 = 0.9994..., i.e. one orbit visits over 99.9% percent of all the Cat(12) structures of size 12, leaving only 208012 - 207882 = 130 structures for other A127296(12)-1 = 9 cycles. Cf. A127298.
