+## Operators That Repeat Work (or might seem like they do)
+
+### Cheap
+
+- Common
+    - `mirrorAxes`
+    - `mirrorOctant`
+    - `mirrorQuadrant`
+    - `modulo1D`
+    - `modulo2D`
+    - `modulo3D`
+    - `moduloPolar`
+    - `reflect`
+- Unusual
+    - `geometricSeriesSquareTile`
+    - `logPolarRepeat`
+    - `moduloDistance`
+    - `moduloSpherical`
+    - `moduloLine`
+    - `quadTreeRepeat`
+    - `rectangleRepeat`
+
+### Expensive
+
+- Common
+    - `gridClone` → `modulo2D`
+    - `instance`
+    - `linearClone` → `modulo1D`
+    - `radialClone` → `moduloPolar`
+- Unusual
+    - `circularRepeat` but only 4x regardless of spacing/radius
+    - `flip` with merge enabled
+    - `instanceField`
+    - `iteratedTransform` with accumulation enabled
