Hi Xypron,

The plain set may have arbitrary dimension, i.e. arbitrary number
of indices are allowed. It is only required that the dimension of the
set to be defined (i.e. the number of its subscripts) plus its arity
must be equal to the arity of the plain set specified. Integers
within parentheses is a permutation of 1, 2, ..., n, where n is the
arity of the plain set. This permutation specifies which components
of every tuple from the plain set become member indices, and which
ones become components of new tuples.
(I plan to make a new release in the new year. However, if you are
interested in allocating a pre-release on your web site for testing
purposes, I could post you the distribution tarball.)
Best,
Andrew Makhorin
