Comments

Double zeros, "00", occur before 27s in the sequence but have been replaced here by 0's.
The roulette wheel and the dartboard are good candidates for what might be considered an "Anti-Gray Code", a sequence of objects from a combinatorial family such that nearby elements are far apart in some metric.

The angular spacing on the rotor between the red numbers 3 and 32 is 6*Pi/37 due to the inserted black 26 and the zero. The spacing of all other red neighbors is 4*Pi/37 due to one inserted black number.
