How many people must be present by Hataras Nedarim, 10 or 11?[1]

The Poskim^[2] rule that it is proper to perform Hataras Nedarim with a group of ten men. Some Poskim[3] understand this to mean that one should have 10 people annul the vow for each individual, hence having a total of 11 in each group. This is done in order to annul the vows of a dream which must be done by ten men. Other Poskim[4], however, imply that a Minyan of ten men suffices in total, with one person asking for the annulment and another nine answering.

Opinion of Admur in Siddur: In the Hataras Nedarim of Admur, no mention is made of the vows of dreams, and thus it is difficult to suggest that this is Admur’s reasoning. [Rav Raskin ibid; Nitei Gavriel ibid] The Rebbe rather explains that a Minyan is needed in order to be able to be Mitaken the world prior to Rosh Hashanah. [Likkutei Sichos 4:1332] The difference between the two explanations is that according to the first explanation a Minyan is needed in addition to the person saying the Hatara, while according to the latter explanation the person saying it is joined together with those being Matir for there to be a Minyan.
