So the Hanafis think that even if there is a group of 100 women that need to pray they need to get a man to lead them all.

"The Islamic recommendation to offer prayers in congregation in the mosque applies to men only. The Prophet (SAAS) advised women to offer their prayers at home, in the most secluded corner of the house... however, women are not banned from the mosque altogether (despite certain cultural practices among Muslims!). If the intention is to pray and learn, then we can go. The Prophet (SAAS) told the men not to forbid the women if they wanted to go to the mosque... The rule about men praying in the front rows and women praying at the back applies to prayer at home, too. Even a husband and wife shouldn't form one row in prayer... A woman cannot lead a mixed congregation in prayer, but when there are only women present, one of them can lead the others. Thus, although we don't have to attend prayers in the mosque, we need not miss out on the benefits and rewards of congregational prayer. When a woman leads others in prayer, she should stand in the middle of the row, not out in front like a male Imam. If there is only one other woman present, she should stand to the right of the "Imam". The woman on the right should recite the Iqama (call immediately preceding prayers)." (source: The Muslim Woman's Handbook by Huda Khattab, 1994, pp. 1-4)

Women, children, the sick and those who care for them, the very old and the blind do not need to pray in congregation (source: Ta'leemul Haq, 2011, p.103).
