[sage-devel] computing the number of partitions of an integer

2007-07-25 Thread William Stein
Hi, Since we were recently discussing speed of computing Bell numbers, maybe it would be interesting to discuss computing the number of partitions of an integer as a sum of other positive integers, i.e., sage: number_of_partitions(5) 7 sage: v = list(partitions(5)); v [(1, 1, 1, 1, 1

You probably know this already but the 2003 survey www.math.rwth-aachen.de/~Gerhard.Hiss/Preprints/AlgoRepTheo.pdf discusses briefly what is/was out there. I don't think it mentions recent packages such as laguna, crime, and hap, but I don't know of a more recent survey. On 7/25/07, Dan Christen

I don't know if this is related to what the original poster wants, but I've been wondering lately whether there is software for doing computations in modular representation theory (where the characteristic of the field divides the order of the group). For example, computations in the ring kG for
