Appears in sequences

• Consider all integer triples (i,j,k), j,k>0, with i^3=j^3+binomial(k+2,3), ordered by increasing i; sequence gives j values.at n=25A054235
• Numbers n such that phi(4n+1) = sigma(n).at n=10A067234
• Product of next n numbers divided by the largest factorial divisor.at n=7A094336
• Number of 3 X n 0..1 arrays with rows, diagonals and antidiagonals unimodal and columns nondecreasing.at n=14A223839
• 1/a(n) is the area of the smallest triangle delimited by 3 lines each passing through at least 2 points of an n X n unitary spaced grid.at n=4A234566
• Distinct values of A378664(k) in the order of appearance, when k ranges over those primitively abundant numbers k for which A378664(k) is less than the largest proper divisor of k.at n=15A378740
