+# Программа распределения участников форума по столам
+
+<img src="https://www.romanovles.ru/upload/iblock/22a/22a396f30e4afd5d76ff53f32834289b.jpg"/>
+
+* Каждому участнику на бейджике пишется номер, у каждого стола есть буква.
+* После доклада оглашается распределение по столам: какой номер, за какой стол садится.
+* Каждый раз по разному.
+* Программа старается сделать так, чтобы каждый посидел за столом с максимально возможным числом различных участников или чтобы все познакомились со всеми.
