Definition:
1. The ordinal number symbol: 17.
2. The position in a sequence following the sixteenth (sextantal) element; the seventh (septal) in the second decimal series.
3. Pertaining to a group, set, or division of seventeen (septant) parts or members.
4. Denoting a prime number value, one beyond a perfect square (16), often representing irregular or prime-numbered groupings.
