Description (last modified by )
The formula should read:
p_i^{(a)} = ( \alpha_a  \lambda^{(i)} )  \sum_{j > i} (j  i) L_j^{(a)}.
The old formula caused the multiplicities to become too large.

It's faster to do it this way:
sage: B = [[1,2]]*50 sage: %timeit for (r,s) in B: r,s 100000 loops, best of 3: 6.61 µs per loop sage: %timeit for b in B: b[0], b[1] 10000 loops, best of 3: 22.4 µs per loop
