It must have cost a pretty penny.
Is this using past participle? |

Hi,
In the idiom mentioned above -'it must have cost a pretty penny'. 'have cost' is a perfect infinitive. After 'must' the verb is always in the infinitive form as in: It must cost. 'It must have to' is a sort of repetition because 'must' and 'have to' both suggest necessity and in that sense the sentence doesn't really make much sense.

Can "to" be left out here?
'it must have (to) cost a pretty penny' right? |

'To' is not needed.
