Pui

Function: pui (<L>, <sym>, <lvar>) decomposes the symmetric polynomial <sym>, in the variables in the list <lvar>, in terms of the power functions in the list <L>. If the first element of <L> is given, it will be the size of the alphabet, otherwise the size will be the degree of the polynomial <sym>. If values are missing in the list <L>, formal values of the type <p1>, <p2> , etc. will be added. The polynomial <sym> may be given in three different forms: contracted (elem should then be 1, its default value), partitioned (elem should be 3), or extended (i.e. the entire polynomial, and elem should then be 2). The function pui is used in the same way.
