In all forms of COMB only the number of combinations is displayed when RESULTS=0 is given. Example: COMB P1,CUR+1 / P1=PARTITIONS,70,14 RESULTS=0 Partitions 14 of 70: N[P1]=290071 ................................................................................ COMB P2,CUR+1 / P2=PARTITIONS,70 MAX=14 RESULTS=0 Partitions of 70: N[P2]=1614987 ................................................................................ COMB P3,CUR+1 / P3=PARTITIONS,70 MAX=13 RESULTS=0 Partitions of 70: N[P3]=1324916 Note: difference N[P2]-N[P3]=290071 = N(P1) (Why?) ................................................................................ By giving RESULTS=1 the list will be displayed but the first line (header line containing N[P]) not. C = Other forms of COMB
