The simplest formula for a two-level nested design is resp~fac1/fac2 All of the models you list are equivalent to this after allowing for the fact that R drops duplicated model terms. For example, fac1+fac1/fac2 expands to fac1 + fac1 + fac1:fac2 ... which reduces to fac1+fac1:fac2. All this is specified in some detail in ?formula.
