1) Use an alias (https://www.gams.com/latest/docs/UG_Set ... mesForASet): alias (i,i1,i2). Declare everything with i and use it in the algebra as needed.
2) Use not sameas(i1,i2) (https://www.gams.com/latest/docs/UG_Con ... eywdSameas) in a $ condition (https://www.gams.com/latest/docs/UG_Con ... rCondition): sum((j,i1,i2)$(not sameas(i1,i2)), ...)
