On equiangular lines in 17 dimensions and the characteristic polynomial of a Seidel matrix

For e a positive integer, we find restrictions modulo 2e on the coefficients of the characteristic polynomial χS(x) of a Seidel matrix S. We show that, for a Seidel matrix of order n even (resp., odd), there are at most 2(e−2 2) (resp., 2((e−2 2)+1) possibilities for the congruence class of χS(x) mo...
