ECore(H|e, mu)
The e-core of a partition mu is what remains after as many rim
e-hooks as possible have been removed from the diagram of mu
(that this is well defined is not obvious; see [JK]). Thus,
ECore(mu) returns the e--core of the partition mu,
gap> H:=Specht(6);; ECore(H,16,8,6,5,3,1); [ 4, 3, 1, 1 ]
The e--core is calculated here using James' notation of an
abacus; there is also an EAbacus function; but it is more
``pretty'' than useful.
See also IsECore IsECore, EQuotient EQuotient, and EWeight
EWeight. This function requires the package ``specht'' (see
RequirePackage).
