W. Lang, M. Sjodahl, Mar 06 2009 A145573 tabf array: characteristic partition array for partitons without part 1. The array is filled with zeros for k>=p(n)= A000041(n). Partitions of n listed in Abramowitz-Stegun (A-St) order p. 831-2 (see the main page for an A-number with the reference). n\k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 ... 1 0 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 1 0 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 1 0 0 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 4 1 0 1 0 0 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 1 0 1 0 0 0 0 | 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 6 1 0 1 1 0 0 1 0 0 0 0 | 0 0 0 0 0 0 0 0 0 0 0 7 1 0 1 1 0 0 0 1 0 0 0 0 0 0 0 | 0 0 0 0 0 0 0 8 1 0 1 1 1 0 0 0 1 1 0 0 0 0 1 0 0 0 0 0 0 0 | . . . n\k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 .. The next two rows, for n=9 and n=10, are (for k=1..p(n)=A000041(n)): n=9: [1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. n=10: [1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. The row sums give A002865(n), n>=1: [0, 1, 1, 2, 2, 4, 4, 7, 8, 12,...] ############################################### e.o.f. ##############################################################################
