I cannot say, it depend on ferrite rod used.
But you can establish approximate number of turns this way:
Turn up ten turn of wire on your ferrite rod.
Measure inductance of those windings.
Divide 57mH by measured inductance (expressed in mH) and then multiply results by 10.
End-result is your approximate number of turns needed.
