The seventy-two elders
The Letter of Aristeas, written about a century later, tells that Demetrius of Phalerum urged Ptolemy II to add the laws of the Jews to the king's library, and that seventy-two elders, six from each tribe, translated them in seventy-two days.

What the evidence supports
The Greek of the Pentateuch is the Greek of Ptolemaic Egypt, and a translation in Alexandria in the 3rd century BCE is secure. Whether the court had any part in it, and whether it was ever placed in the Library, is unknown.
