Note that the union of all bases over all n extends to a universal basis
The rank (number of elements in basis) is 2
See Algorithm 2.4 for details
Note that equality is modulo multiplication by an nth unit root and modulo dth cyclotomic units where d is a proper divisor of n.1: v(15,1) is in basis
Compare with Algorithm 1.2 and 2.2
1: v(15,1) - method B (Case V,i - A12)
2: v(15,2) - method Z-3 (Case V,iv - A12)
4: v(15,4) - method Z-5 (Case V,iv - A12)
7: v(15,7) - method S (Case V,ii - A12 for p=5)
8: v(15,8) - method Z-3 (Case V,iv - A12)
11: v(15,11) - method Z-3 (Case V,iv - A12)
13: v(15,13) - method B (Case V,iii - A12)
14: v(15,14) - method Z-3 (Case V,iv - A12)
