 `𝕩` is an array. `𝕨` is a number or numeric list or scalar with `𝕨≤○≠≢𝕩`. The result `z` has shape `𝕨∾¬⟜𝕨⌾((≠𝕨)⊸↑)≢𝕩`, and element `i⊑z` is `𝕩⊑˜(≠𝕨)(↑+⌾((≠𝕨)⊸↑)↓)i`.
 
-Using [Group](group.md) we could also write `i⊑z` ←→ `𝕩⊑˜(𝕨∾○(↕∘≠)≢𝕩) (>+´¨)∘⊔ i`.

 This method extends to any number of initial elements. We can modify the running sum above to keep the length constant by starting with two zeros.
