PART::Part2Border
--
border of a given partition
PART::Part2Border(part <,alphabet=m>)
part | - | a partition |
alphabet=m | - | returns the same, m[1] denoting horizontal steps, m[2] vertical ones |
Use the syntax hold(identifier)
, instead of
identifier
, if one of the identifiers above is already
defined.
The PART::Part2Border
function gives the border of the diagram of a
partition part
.
The border is a list of 0 (horizontal steps) and 1 (vertical steps). border of part, 1 a vertical one.
