The integer constants for the inversions have explicit formulas in terms of sums of integer products as well as a simple algorithm iterating a Lie derivative involving only integers--can be translated into summing over different varieties of trees or dissections of polygons or as the antipode of a comb. Hopf alg. Now how is the square root calculated and when does the algorithm stop for an irrational number? I find the set of integers, each calculable exactly through a finite number of additions or multiplications, with diverse comb. interpretations more satisfying. | |
