: [FLags] Output Simplify: Minimun. Increasing (a): Off = decreassing 2...1

factor(a^3-b^3, a) => (a^0-b)*(a^2+a^1*b+a^0*b^2) OK the variable a, is first that b

: [FLags] Output Simplify: Minimun. Increasing (b): Off = decreassing 2...1

factor(a^3-b^3, b) => -(b^0-a)*(b^2+b^1*a+a^2*b^0) OK the variable b, is first that a

But, control is lost in the following case

: [FLags] Output Simplify: Minimun. Increasing (a): On

factor(a^3-b^3, a) => (-b+a^0)*(a^0*b^2+a*b+a^2)

The factor (a^0*b^2+a^1*b+a^2) is OK, but no (-b+a)

the output must be

: [FLags] Output Simplify: Minimun. Increasing (a): On

factor(a^3-b^3, a) => (a^0-b)*(a^0*b^2+a*b+a^2)
