Note that the union of all bases over all n extends to a universal basis
v(9,4), v(9,7)
The rank (number of elements in basis) is 2
v(9,4) | v(9,7) | |
v(9,1) | ||
v(9,2) | 1 | |
v(9,5) | 1 | |
v(9,8) |
Note that equality is modulo multiplication by an n^{th} unit root and modulo d^{th} cyclotomic units where d is a proper divisor of n.
1: v(9,1) = 1 1: v(9,1) - method T (Case IV,iii - A22)
2: v(9,2) - method S (Case IV,i - A22)
4: v(9,4) - method B (Case IV,ii - A22)
5: v(9,5) - method S (Case IV,i - A22)
7: v(9,7) - method B (Case IV,ii - A22)
8: v(9,8) - method S (Case IV,i - A22)
