There are twenty students in your class and eight teachers teach you. A photograph of your class is to be
taken with your teachers and principal in such a way that all teachers and principal sit in the first row and
all students stand in second row. If the middle seat of the first row is reserved for the principal and the two
corners of the second row and reserved for two tallest students interchangeable only between them, then
how many seating arrangements are possible?
