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(16,1) = 1
Compare with Algorithm 2.2
1: v(16,1) - method T (Case IV,iii - A22)
3: v(16,3) - method Y-2 (Case IV,iv - A22)
5: v(16,5) - method S (Case IV,i - A22)
7: v(16,7) - method S (Case IV,i - A22)
9: v(16,9) - method B (Case IV,ii - A22)
11: v(16,11) - method B (Case IV,ii - A22)
13: v(16,13) - method S (Case IV,i - A22)
15: v(16,15) - method S (Case IV,i - A22)
