Alois P. Heinz, Table of n, a(n) for n = 0..100

MAPLE

A:= proc(n) option remember; if n=0 then 1 else unapply (convert (series (exp (x* A(n-1)(sin(x))), x, n+1), polynom), x) fi end; a:= n-> coeff (A(n)(x), x, n)*n!: seq (a(n), n=0..20);

MATHEMATICA

A[n_] := A[n] = If[n == 0, 1, Normal[Series[Exp[x*A[n-1][Sin[x]]], {x, 0, n+1}]] /. x -> #]&; a[n_] := Coefficient[A[n][x], x, n]*n!; Table[a[n], {n, 0, 20}] (* Jean-Fran├žois Alcover, Feb 14 2014, after Maple *)
