A [[Sudoku]] puzzle is locally minimal when removing any of its [[given]]s results in a puzzle that has multiple solutions.

Locally minimal is not the same as [[minimal]]. The same solution grid can contain a puzzle with fewer givens, but that puzzle will contain at least one given which does not belong to the locally minimal puzzle.

A puzzle is [[symmetrically minimal]] when it cannot be reduced within the [[symmetry]] restrictions.
