Abstract
Pachner move 3 –> 3 deals with triangulations of four-dimensional manifolds. We present an algebraic relation corresponding in a natural way to this move and based, a bit paradoxically, on three-dimensional geometry.

Key words: piecewise-linear topology; Pachner move; algebraic relation; three-dimensional affine geometry.
