It’s anathema to try to think of ways to blaspheme.
Suffice it to say that that is between the individual and God.
It beggs the question why one would want to know; we can apply charity and assume it is simply to avoid such. If that is is the case, may I suggest a game of brinkmanship with the Almighty is ill-advised at best. If, on the other hand one wishes to have such knowledge in order to do that very act; it would be sin on anyone’s part to help one in their endeavor.
