I don't know what this option actually does, but both seem to work. sage: groups.misc.AdditiveAbelian([2,2,2,3],remember_generators=False)(vector([1,1,1,1])) (1, 1, 1, 1) sage: groups.misc.AdditiveAbelian([2,2,2,3],remember_generators=True)(vector([1,1,1,1])) (1, 1, 1, 1)
Also, why should vector([1,1,1,1]) be recognised and not [1,1,1,1] ?
