Many of the functions in Specht take partitions as arguments. Partitions are usually represented by lists in GAP. In Specht, all the functions which expect a partition will accept their argument either as a list or simply as a sequence of numbers. So, for example:
gap> H:=Specht(4);; H.S(H.P(6,4)); S(6,4)+S(6,3,1)+S(5,3,1,1)+S(3,3,2,1,1)+S(2,2,2,2,2) gap> H.S(H.P([6,4])); S(6,4)+S(6,3,1)+S(5,3,1,1)+S(3,3,2,1,1)+S(2,2,2,2,2)
Some functions require more than one argument, but the convention still applies.
gap> ECore(3, [6,4,2]); [ 6, 4, 2 ] gap> ECore(3, 6,4,2); [ 6, 4, 2 ] gap> GoodNodes(3, 6,4,2); [ false, false, 3 ] gap> GoodNodes(3, [6,4,2], 2); 3
Basically, it never hurts to put the extra brackets in, and they can
be omitted so long as this is not ambiguous. One function where the
brackets are needed is
DecompositionNumber; this is clear because
the function takes two partitions as its arguments.
