Line 2,928:
Two versions of ''classifications'' of ''non-terminating'' are used:
::* (lowercase) '''non-terminating''' ─── due to more than sixteen cyclic numbers
::* (uppercase) '''NON-TERMINATING''' ─── due to a cyclic number that is larger than <big>2<sup>47</sup></big>
Both of the above limitations are imposed by this Rosetta Code task's restriction requirements: ''For the purposes of this task, ···''.
