basisOfSymmetricCurves -- produces a basis of symmetric curves

Synopsis

Description

This function returns the list of F curves {F1,1,i,n-i-2: 1 ≤i ≤[n/2]}. This set of curves is a basis for H2(M0,n)QSn; see e.g. [AGSS]. The symmetric F-curve F1,1,i,n-i-2 is represented by the list of integers {1,1,i,n-i-2}.
