Order-7-3 triangular honeycomb ideal boundary) with infinitely many order-7 triangular tilings existing around each vertex in an "order-6 heptagonal tiling", {7,6}, vertex figure. In the geometry of hyperbolic 3-space, the order-7-infinite triangular honeycomb (or 3,7,∞ honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {3,7,∞}. It has infinitely many order-7 triangular tiling, {3,7}, around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many order-7 triangular tilings existing around each vertex in an "infinite-order heptagonal tiling", {7,∞}, vertex figure. It has a second construction as a uniform honeycomb, Schläfli symbol {3,(7,∞,7)}, Coxeter diagram, = , with alternating
