A flag of a finite dimensional vector space V is a nested sequence of subspaces
of V . The symplectic group of V acts on the set of flags of V . We classify the
orbits of this action by defining the incidence matrix of a flag of V and show-
ing that two flags are in the same orbit precisely when they have the same
incidence matrix. We give a formula for the number of orbits of a certain
type and discuss how to list the incidence matrices of all orbits. In the case
in which V is a vector space over a finite field, we discuss the permutation
representations of the symplectic group of V corresponding to these orbits.
For the case in which V = (F_q)^4 , we compute the conjugacy classes of the sym-
plectic group of V and the values of the characters of the previously discussed
permutation representations. / Mathematics
