TYP::IsSkewPart
--
tests whether the argument is a skew partition
TYP::IsSkewPart(expr)
expr | - | any expression |
The TYP::IsSkewPart
function tests whether expr
is a skew partition that is a
a list with two components l1
and l2
, l1
being the exterior
shape, l2
the interior shape.
The diagram of bixes needs not to be connected, the condition being that the
diagram of l2
must be included into the one of l1
.
