OEIS Sequences

Square table, read by antidiagonals, where row e.g.f.s, R(n,x), satisfy: d/dx log( R(n,x) )/n = R(n+1,x) with R(n,0) = 1; that is, the logarithmic derivative of the e.g.f. of row n, divided by n, equals the e.g.f. of row n+1, for n>=1. A145080

Semiperimeter of primitive Pythagorean triangles having legs that add up to a square, sorted on hypotenuse. A89549

Indices of primes in sequence defined by A(0) = 17, A(n) = 10·A(n-1) - 63 for n > 0. A102007
