start: S(18)

S(n) --> S((n+(3^i*6+i+4))/2), n mod 2 = i mod 2, 3^i*2-i-2 <= n <= 3^i*6-i-6
S(n) --> S(3^i*12-1), n mod 2 = (i+1) mod 2, 3^i*2-i <= n <= 3^i*6-i-10

These rules are closed if

(3^i*2+i+5)/(2^v2(3^i*2+i+5))>=2i+14 for all i>=50 

Further Analysis (Pomme, Autumn Pan, et al.)

Although it has not been proven in Rocq, it is known that the inequality holds. This has been proven informally by Pomme, and an alternative proof is underway by Autumn Pan.
