Detailed Description

A single einsum dimension's contribution to one operand's access subset.

The dimension's induction variable appears in exactly one index position of the operand's subset, scaled by an integer factor to support linearized accesses (e.g. i in [k + i*8] contributes to index position 0 with factor 8).
