We obtain the universal R-matrix of the nonstandard quantum group asso
ciated to the Alexander-Conway knot polynomial. We show further that t
his nonstandard quantum group is related to the super-quantum group U-
q gl(1/1) by a general process of superization, which we describe. We
also study a twisted variant of this nonstandard quantum group and obt
ain, as a result, a twisted version of U-q gl(1/1) as a q supersymmetr
y of the exterior differential calculus of any quantum plane of Hecke
type, acting by mixing the bosonic x(i) coordinates and the forms dx(i
). (C) 1995 American Institute of Physics.
