    Default Passive form of "must have+past participle"

    Hi
    Could you kindly help me with the passive form of the following sentence?
    A man must have rubbed the bank. Can we say "the bank must have been being rubbed by a man"?

    Thanks a million.
    Being a non-native teacher, I'm so thrilled being in such a superb forum.

    It's right now.
    Your original answer is the passive form of "A man must have been robbing the bank".

    Oops! I goofed! for the typo. Thanks a lot. Could you kindly tell me what the difference is between the two sentences? must have robbed and must have been robbing. Do we just emphasize on the continuation of the action in "must have been robbing"?

    Thanks.

    Thanks.
    Yes, it's the progressive form. (You took a non-progressive active sentence and introduced the progressive in the passive sentence.)
    If something happened while the man was robbing the bank, you'd use the progressive form for robbing, and the simple past for the other event:
    "The man must have been robbing the bank when he was shot."
