 OFFSET 1,3 COMMENTS Triangle of numbers P(n,k) begins: .............................1/2 ......................1/3...........7/9 ...............1/4...........5/8............29/32 .........1/5.........13/25.........101/125..........601/625 ...1/6.........4/9..........13/18...........49/54...............319/324 LINKS EXAMPLE a(8) = 13 because 13 is numerator of 13/25 = P(3,5) = T( a(15) = 319 because 319 is numerator of 319/324 = P(6,6) CROSSREFS Cf.
