Ner Yisroel still maintains a special minyan on Shabbos for Persian students. Communal prayer requires a quorum of ten adult Jews, called a "minyan". All public prayer requires a minyan, a quorum of 10 adults, to be present. Amidah or when a minyan is not present. Orthodox Judaism still follows this reasoning and excludes women from the minyan. There is also a student-led egalitarian minyan which holds services on Friday evenings. The most common activity requiring a "minyan" is public prayer. Early sources dispute whether this kedushah may be recited by individuals praying without a minyan. Along with some prayers, it can only be recited with a minyan of ten Jews. The Barechu is only recited in the presence of a minyan. The source for the requirement of "minyan" is recorded in the Talmud. The word "minyan" itself comes from the Hebrew root meaning to count or to number. His inclusion in "minyan" is thus subject of Talmudic dispute. The ceremony traditionally takes place before a minyan of 10 men. However, the stress is put upon the merits and sacredness of the "minyan" of ten.
