P(), Q(),
R(), and S() give the number of partitions, unequal
partitions, restricted partitions, and block partitions of an integer.Functions parts(), diffparts(), restrictedparts(),
and blockparts() enumerate these partitions.
Function conjugate() gives the conjugate of a partition and
function durfee() gives the size of the Durfee square.
NB the emphasis in this package is terse, efficient C code.
This means that there is a minimum of argument checking. For example,
function conjugate() assumes that the partition is in standard
form (ie nonincreasing); supplying a vector in nonstandard form will
result in garbage being returned silently. Note that a block partition
is not necessarily in standard form.
